 Finally, the [KMG] suffix is commonly described after a number of kernel
 parameter values. These 'K', 'M', and 'G' letters represent the _binary_
 multipliers 'Kilo', 'Mega', and 'Giga', equalling 2^10, 2^20, and 2^30
-bytes respectively. Such letter suffixes can also be entirely omitted::

-
-	acpi=		[HW,ACPI,X86,ARM64]
-			Advanced Configuration and Power Interface
-			Format: { force | on | off | strict | noirq | rsdt |
-				  copy_dsdt }
-			force -- enable ACPI if default was off
-			on -- enable ACPI but allow fallback to DT [arm64]
-			off -- disable ACPI if default was on
-			noirq -- do not use ACPI for IRQ routing
-			strict -- Be less tolerant of platforms that are not
-				strictly ACPI specification compliant.
-			rsdt -- prefer RSDT over (default) XSDT
-			copy_dsdt -- copy DSDT to memory
-			For ARM64, ONLY "acpi=off", "acpi=on" or "acpi=force"
-			are available
-
-			See also Documentation/power/runtime_pm.txt, pci=noacpi
-
-	acpi_apic_instance=	[ACPI, IOAPIC]
-			Format: <int>
-			2: use 2nd APIC table, if available
-			1,0: use 1st APIC table
-			default: 0
-
-	acpi_backlight=	[HW,ACPI]
-			acpi_backlight=vendor
-			acpi_backlight=video
-			If set to vendor, prefer vendor specific driver
-			(e.g. thinkpad_acpi, sony_acpi, etc.) instead
-			of the ACPI video.ko driver.
-
-	acpi_force_32bit_fadt_addr
-			force FADT to use 32 bit addresses rather than the
-			64 bit X_* addresses. Some firmware have broken 64
-			bit addresses for force ACPI ignore these and use
-			the older legacy 32 bit addresses.
-
-	acpica_no_return_repair [HW, ACPI]
-			Disable AML predefined validation mechanism
-			This mechanism can repair the evaluation result to make
-			the return objects more ACPI specification compliant.
-			This option is useful for developers to identify the
-			root cause of an AML interpreter issue when the issue
-			has something to do with the repair mechanism.
-
-	acpi.debug_layer=	[HW,ACPI,ACPI_DEBUG]
-	acpi.debug_level=	[HW,ACPI,ACPI_DEBUG]
-			Format: <int>
-			CONFIG_ACPI_DEBUG must be enabled to produce any ACPI
-			debug output.  Bits in debug_layer correspond to a
-			_COMPONENT in an ACPI source file, e.g.,
-			    #define _COMPONENT ACPI_PCI_COMPONENT
-			Bits in debug_level correspond to a level in
-			ACPI_DEBUG_PRINT statements, e.g.,
-			    ACPI_DEBUG_PRINT((ACPI_DB_INFO, ...
-			The debug_level mask defaults to "info".  See
-			Documentation/acpi/debug.txt for more information about
-			debug layers and levels.
-
-			Enable processor driver info messages:
-			    acpi.debug_layer=0x20000000
-			Enable PCI/PCI interrupt routing info messages:
-			    acpi.debug_layer=0x400000
-			Enable AML "Debug" output, i.e., stores to the Debug
-			object while interpreting AML:
-			    acpi.debug_layer=0xffffffff acpi.debug_level=0x2
-			Enable all messages related to ACPI hardware:
-			    acpi.debug_layer=0x2 acpi.debug_level=0xffffffff
-
-			Some values produce so much output that the system is
-			unusable.  The "log_buf_len" parameter may be useful
-			if you need to capture more output.
-
-	acpi_enforce_resources=	[ACPI]
-			{ strict | lax | no }
-			Check for resource conflicts between native drivers
-			and ACPI OperationRegions (SystemIO and SystemMemory
-			only). IO ports and memory declared in ACPI might be
-			used by the ACPI subsystem in arbitrary AML code and
-			can interfere with legacy drivers.
-			strict (default): access to resources claimed by ACPI
-			is denied; legacy drivers trying to access reserved
-			resources will fail to bind to device using them.
-			lax: access to resources claimed by ACPI is allowed;
-			legacy drivers trying to access reserved resources
-			will bind successfully but a warning message is logged.
-			no: ACPI OperationRegions are not marked as reserved,
-			no further checks are performed.
-
-	acpi_force_table_verification	[HW,ACPI]
-			Enable table checksum verification during early stage.
-			By default, this is disabled due to x86 early mapping
-			size limitation.
-
-	acpi_irq_balance [HW,ACPI]
-			ACPI will balance active IRQs
-			default in APIC mode
-
-	acpi_irq_nobalance [HW,ACPI]
-			ACPI will not move active IRQs (default)
-			default in PIC mode
-
-	acpi_irq_isa=	[HW,ACPI] If irq_balance, mark listed IRQs used by ISA
-			Format: <irq>,<irq>...
-
-	acpi_irq_pci=	[HW,ACPI] If irq_balance, clear listed IRQs for
-			use by PCI
-			Format: <irq>,<irq>...
-
-	acpi_no_auto_serialize	[HW,ACPI]
-			Disable auto-serialization of AML methods
-			AML control methods that contain the opcodes to create
-			named objects will be marked as "Serialized" by the
-			auto-serialization feature.
-			This feature is enabled by default.
-			This option allows to turn off the feature.
-
-	acpi_no_memhotplug [ACPI] Disable memory hotplug.  Useful for kdump
-			   kernels.
-
-	acpi_no_static_ssdt	[HW,ACPI]
-			Disable installation of static SSDTs at early boot time
-			By default, SSDTs contained in the RSDT/XSDT will be
-			installed automatically and they will appear under
-			/sys/firmware/acpi/tables.
-			This option turns off this feature.
-			Note that specifying this option does not affect
-			dynamic table installation which will install SSDT
-			tables to /sys/firmware/acpi/tables/dynamic.
-
-	acpi_rsdp=	[ACPI,EFI,KEXEC]
-			Pass the RSDP address to the kernel, mostly used
-			on machines running EFI runtime service to boot the
-			second kernel for kdump.
-
-	acpi_os_name=	[HW,ACPI] Tell ACPI BIOS the name of the OS
-			Format: To spoof as Windows 98: ="Microsoft Windows"
-
-	acpi_rev_override [ACPI] Override the _REV object to return 5 (instead
-			of 2 which is mandated by ACPI 6) as the supported ACPI
-			specification revision (when using this switch, it may
-			be necessary to carry out a cold reboot _twice_ in a
-			row to make it take effect on the platform firmware).
-
-	acpi_osi=	[HW,ACPI] Modify list of supported OS interface strings
-			acpi_osi="string1"	# add string1
-			acpi_osi="!string2"	# remove string2
-			acpi_osi=!*		# remove all strings
-			acpi_osi=!		# disable all built-in OS vendor
-						  strings
-			acpi_osi=!!		# enable all built-in OS vendor
-						  strings
-			acpi_osi=		# disable all strings
-
-			'acpi_osi=!' can be used in combination with single or
-			multiple 'acpi_osi="string1"' to support specific OS
-			vendor string(s).  Note that such command can only
-			affect the default state of the OS vendor strings, thus
-			it cannot affect the default state of the feature group
-			strings and the current state of the OS vendor strings,
-			specifying it multiple times through kernel command line
-			is meaningless.  This command is useful when one do not
-			care about the state of the feature group strings which
-			should be controlled by the OSPM.
-			Examples:
-			  1. 'acpi_osi=! acpi_osi="Windows 2000"' is equivalent
-			     to 'acpi_osi="Windows 2000" acpi_osi=!', they all
-			     can make '_OSI("Windows 2000")' TRUE.
-
-			'acpi_osi=' cannot be used in combination with other
-			'acpi_osi=' command lines, the _OSI method will not
-			exist in the ACPI namespace.  NOTE that such command can
-			only affect the _OSI support state, thus specifying it
-			multiple times through kernel command line is also
-			meaningless.
-			Examples:
-			  1. 'acpi_osi=' can make 'CondRefOf(_OSI, Local1)'
-			     FALSE.
-
-			'acpi_osi=!*' can be used in combination with single or
-			multiple 'acpi_osi="string1"' to support specific
-			string(s).  Note that such command can affect the
-			current state of both the OS vendor strings and the
-			feature group strings, thus specifying it multiple times
-			through kernel command line is meaningful.  But it may
-			still not able to affect the final state of a string if
-			there are quirks related to this string.  This command
-			is useful when one want to control the state of the
-			feature group strings to debug BIOS issues related to
-			the OSPM features.
-			Examples:
-			  1. 'acpi_osi="Module Device" acpi_osi=!*' can make
-			     '_OSI("Module Device")' FALSE.
-			  2. 'acpi_osi=!* acpi_osi="Module Device"' can make
-			     '_OSI("Module Device")' TRUE.
-			  3. 'acpi_osi=! acpi_osi=!* acpi_osi="Windows 2000"' is
-			     equivalent to
-			     'acpi_osi=!* acpi_osi=! acpi_osi="Windows 2000"'
-			     and
-			     'acpi_osi=!* acpi_osi="Windows 2000" acpi_osi=!',
-			     they all will make '_OSI("Windows 2000")' TRUE.
-
-	acpi_pm_good	[X86]
-			Override the pmtimer bug detection: force the kernel
-			to assume that this machine's pmtimer latches its value
-			and always returns good values.
-
-	acpi_sci=	[HW,ACPI] ACPI System Control Interrupt trigger mode
-			Format: { level | edge | high | low }
-
-	acpi_skip_timer_override [HW,ACPI]
-			Recognize and ignore IRQ0/pin2 Interrupt Override.
-			For broken nForce2 BIOS resulting in XT-PIC timer.
-
-	acpi_sleep=	[HW,ACPI] Sleep options
-			Format: { s3_bios, s3_mode, s3_beep, s4_nohwsig,
-				  old_ordering, nonvs, sci_force_enable }
-			See Documentation/power/video.txt for information on
-			s3_bios and s3_mode.
-			s3_beep is for debugging; it makes the PC's speaker beep
-			as soon as the kernel's real-mode entry point is called.
-			s4_nohwsig prevents ACPI hardware signature from being
-			used during resume from hibernation.
-			old_ordering causes the ACPI 1.0 ordering of the _PTS
-			control method, with respect to putting devices into
-			low power states, to be enforced (the ACPI 2.0 ordering
-			of _PTS is used by default).
-			nonvs prevents the kernel from saving/restoring the
-			ACPI NVS memory during suspend/hibernation and resume.
-			sci_force_enable causes the kernel to set SCI_EN directly
-			on resume from S1/S3 (which is against the ACPI spec,
-			but some broken systems don't work without it).
-
-	acpi_use_timer_override [HW,ACPI]
-			Use timer override. For some broken Nvidia NF5 boards
-			that require a timer override, but don't have HPET
-
-	add_efi_memmap	[EFI; X86] Include EFI memory map in
-			kernel's map of available physical RAM.
-
-	agp=		[AGP]

-	ALSA		[HW,ALSA]
-			See Documentation/sound/alsa/alsa-parameters.txt
-
-	alignment=	[KNL,ARM]
-			Allow the default userspace alignment fault handler

-
-	align_va_addr=	[X86-64]
-			Align virtual addresses by clearing slice [14:12] when
-			allocating a VMA at process creation time. This option
-			gives you up to 3% performance improvement on AMD F15h
-			machines (where it is enabled by default) for a
-			CPU-intensive style benchmark, and it can vary highly in
-			a microbenchmark depending on workload and compiler.
-
-			32: only for 32-bit processes
-			64: only for 64-bit processes
-			on: enable for both 32- and 64-bit processes
-			off: disable for both 32- and 64-bit processes
-
-	alloc_snapshot	[FTRACE]
-			Allocate the ftrace snapshot buffer on boot up when the
-			main buffer is allocated. This is handy if debugging
-			and you need to use tracing_snapshot() on boot up, and
-			do not want to use tracing_snapshot_alloc() as it needs
-			to be done where GFP_KERNEL allocations are allowed.
-
-	amd_iommu=	[HW,X86-64]
-			Pass parameters to the AMD IOMMU driver in the system.
-			Possible values are:
-			fullflush - enable flushing of IO/TLB entries when
-				    they are unmapped. Otherwise they are
-				    flushed before they will be reused, which
-				    is a lot of faster
-			off	  - do not initialize any AMD IOMMU found in
-				    the system
-			force_isolation - Force device isolation for all
-					  devices. The IOMMU driver is not
-					  allowed anymore to lift isolation
-					  requirements as needed. This option
-					  does not override iommu=pt
-
-	amd_iommu_dump=	[HW,X86-64]
-			Enable AMD IOMMU driver option to dump the ACPI table
-			for AMD IOMMU. With this option enabled, AMD IOMMU
-			driver will print ACPI tables for AMD IOMMU during
-			IOMMU initialization.
-
-	amd_iommu_intr=	[HW,X86-64]
-			Specifies one of the following AMD IOMMU interrupt
-			remapping modes:
-			legacy     - Use legacy interrupt remapping mode.
-			vapic      - Use virtual APIC mode, which allows IOMMU
-			             to inject interrupts directly into guest.
-			             This mode requires kvm-amd.avic=1.
-			             (Default when IOMMU HW support is present.)
-
-	amijoy.map=	[HW,JOY] Amiga joystick support
-			Map of devices attached to JOY0DAT and JOY1DAT
-			Format: <a>,<b>
-			See also Documentation/input/joystick.txt
-
-	analog.map=	[HW,JOY] Analog joystick and gamepad support
-			Specifies type or capabilities of an analog joystick
-			connected to one of 16 gameports

-
-	apc=		[HW,SPARC]
-			Power management functions (SPARCstation-4/5 + deriv.)
-			Format: noidle
-			Disable APC CPU standby support. SPARCstation-Fox does
-			not play well with APC CPU idle - disable it if you have
-			APC and your system crashes randomly.
-
-	apic=		[APIC,X86-32] Advanced Programmable Interrupt Controller
-			Change the output verbosity whilst booting
-			Format: { quiet (default) | verbose | debug }
-			Change the amount of debugging information output
-			when initialising the APIC and IO-APIC components.
-
-	apic_extnmi=	[APIC,X86] External NMI delivery setting
-			Format: { bsp (default) | all | none }
-			bsp:  External NMI is delivered only to CPU 0
-			all:  External NMIs are broadcast to all CPUs as a
-			      backup of CPU 0
-			none: External NMI is masked for all CPUs. This is
-			      useful so that a dump capture kernel won't be
-			      shot down by NMI
-
-	autoconf=	[IPV6]
-			See Documentation/networking/ipv6.txt.
-
-	show_lapic=	[APIC,X86] Advanced Programmable Interrupt Controller
-			Limit apic dumping. The parameter defines the maximal
-			number of local apics being dumped. Also it is possible
-			to set it to "all" by meaning -- no limit here.
-			Format: { 1 (default) | 2 | ... | all }.
-			The parameter valid if only apic=debug or
-			apic=verbose is specified.
-			Example: apic=debug show_lapic=all
-
-	apm=		[APM] Advanced Power Management

-			Format: <bool> (0 = real, 1 = synthetic (default))
-
-	atkbd.softrepeat= [HW]
-			Use software keyboard repeat
-
-	audit=		[KNL] Enable the audit sub-system
-			Format: { "0" | "1" } (0 = disabled, 1 = enabled)
-			0 - kernel audit is disabled and can not be enabled
-			    until the next reboot
-			unset - kernel audit is initialized but disabled and
-			    will be fully enabled by the userspace auditd.
-			1 - kernel audit is initialized and partially enabled,
-			    storing at most audit_backlog_limit messages in
-			    RAM until it is fully enabled by the userspace
-			    auditd.
-			Default: unset
-
-	audit_backlog_limit= [KNL] Set the audit queue size limit.
-			Format: <int> (must be >=0)
-			Default: 64
-
-	bau=		[X86_UV] Enable the BAU on SGI UV.  The default
-			behavior is to disable the BAU (i.e. bau=0).
-			Format: { "0" | "1" }

-			1 - Enable the BAU.
-			unset - Disable the BAU.
-
-	baycom_epp=	[HW,AX25]
-			Format: <io>,<mode>
-
-	baycom_par=	[HW,AX25] BayCom Parallel Port AX.25 Modem

-			See header of drivers/net/hamradio/baycom_par.c.
-
-	baycom_ser_fdx=	[HW,AX25]

-			BayCom Serial Port AX.25 Modem (Half Duplex Mode)
-			Format: <io>,<irq>,<mode>
-			See header of drivers/net/hamradio/baycom_ser_hdx.c.
-
-	blkdevparts=	Manual partition parsing of block device(s) for
-			embedded devices based on command line input.
-			See Documentation/block/cmdline-partition.txt
-
-	boot_delay=	Milliseconds to delay each printk during boot.

-			firmware feature for flushing multiple hpte entries
-			at a time.
-
-	c101=		[NET] Moxa C101 synchronous serial card
-
-	cachesize=	[BUGS=X86-32] Override level 2 CPU cache size detection.
-			Sometimes CPU hardware bugs make them report the cache
-			size incorrectly. The kernel will attempt work arounds
-			to fix known problems, but for some CPUs it is not
-			possible to determine what the correct size should be.
-			This option provides an override for these situations.
-
-	ca_keys=	[KEYS] This parameter identifies a specific key(s) on
-			the system trusted keyring to be used for certificate
-			trust validation.
-			format: { id:<keyid> | builtin }
-
-	cca=		[MIPS] Override the kernel pages' cache coherency

-
-	ccw_timeout_log [S390]
-			See Documentation/s390/CommonIO for details.
-
-	cgroup_disable= [KNL] Disable a particular controller
-			Format: {name of the controller(s) to disable}
-			The effects of cgroup_disable=foo are:
-			- foo isn't auto-mounted if you mount all cgroups in
-			  a single hierarchy
-			- foo isn't visible as an individually mountable
-			  subsystem
-			{Currently only "memory" controller deal with this and
-			cut the overhead, others just disable the usage. So
-			only cgroup_disable=memory is actually worthy}
-
-	cgroup_no_v1=	[KNL] Disable one, multiple, all cgroup controllers in v1
-			Format: { controller[,controller...] | "all" }
-			Like cgroup_disable, but only applies to cgroup v1;
-			the blacklisted controllers remain available in cgroup2.
-
-	cgroup.memory=	[KNL] Pass options to the cgroup memory controller.
-			Format: <string>
-			nosocket -- Disable socket memory accounting.
-			nokmem -- Disable kernel memory accounting.
-
-	checkreqprot	[SELINUX] Set initial checkreqprot flag value.
-			Format: { "0" | "1" }
-			See security/selinux/Kconfig help text.
-			0 -- check protection applied by kernel (includes
-				any implied execute protection).
-			1 -- check protection requested by application.
-			Default value is set via a kernel config option.
-			Value can be changed at runtime via
-				/selinux/checkreqprot.
-
-	cio_ignore=	[S390]
-			See Documentation/s390/CommonIO for details.
-	clk_ignore_unused
-			[CLK]
-			Prevents the clock framework from automatically gating
-			clocks that have not been explicitly enabled by a Linux
-			device driver but are enabled in hardware at reset or
-			by the bootloader/firmware. Note that this does not
-			force such clocks to be always-on nor does it reserve
-			those clocks in any way. This parameter is useful for
-			debug and development, but should not be needed on a
-			platform with proper driver support.  For more
-			information, see Documentation/clk.txt.
-
-	clock=		[BUGS=X86-32, HW] gettimeofday clocksource override.
-			[Deprecated]
-			Forces specified clocksource (if available) to be used
-			when calculating gettimeofday(). If specified
-			clocksource is not available, it defaults to PIT.
-			Format: { pit | tsc | cyclone | pmtmr }
-
-	clocksource=	Override the default clocksource
-			Format: <string>
-			Override the default clocksource and use the clocksource
-			with the name specified.
-			Some clocksource names to choose from, depending on
-			the platform:
-			[all] jiffies (this is the base, fallback clocksource)
-			[ACPI] acpi_pm
-			[ARM] imx_timer1,OSTS,netx_timer,mpu_timer2,
-				pxa_timer,timer3,32k_counter,timer0_1
-			[AVR32] avr32
-			[X86-32] pit,hpet,tsc;
-				scx200_hrt on Geode; cyclone on IBM x440
-			[MIPS] MIPS
-			[PARISC] cr16
-			[S390] tod
-			[SH] SuperH
-			[SPARC64] tick
-			[X86-64] hpet,tsc
-
-	clocksource.arm_arch_timer.evtstrm=
-			[ARM,ARM64]
-			Format: <bool>
-			Enable/disable the eventstream feature of the ARM
-			architected timer so that code using WFE-based polling
-			loops can be debugged more effectively on production
-			systems.
-
-	clocksource.arm_arch_timer.fsl-a008585=
-			[ARM64]
-			Format: <bool>
-			Enable/disable the workaround of Freescale/NXP
-			erratum A-008585.  This can be useful for KVM
-			guests, if the guest device tree doesn't show the
-			erratum.  If unspecified, the workaround is
-			enabled based on the device tree.
-
-	clearcpuid=BITNUM [X86]
-			Disable CPUID feature X for the kernel. See
-			arch/x86/include/asm/cpufeatures.h for the valid bit
-			numbers. Note the Linux specific bits are not necessarily
-			stable over kernel options, but the vendor specific
-			ones should be.
-			Also note that user programs calling CPUID directly
-			or using the feature without checking anything
-			will still see it. This just prevents it from
-			being used by the kernel or shown in /proc/cpuinfo.
-			Also note the kernel might malfunction if you disable
-			some critical bits.
-
-	cma=nn[MG]@[start[MG][-end[MG]]]
-			[ARM,X86,KNL]
-			Sets the size of kernel global memory area for
-			contiguous memory allocations and optionally the
-			placement constraint by the physical address range of
-			memory allocations. A value of 0 disables CMA
-			altogether. For more information, see
-			include/linux/dma-contiguous.h
-

-
-	crashkernel=size[KMG][@offset[KMG]]
-			[KNL] Using kexec, Linux can switch to a 'crash kernel'
-			upon panic. This parameter reserves the physical
-			memory region [offset, offset + size] for that kernel
-			image. If '@offset' is omitted, then a suitable offset
-			is selected automatically. Check
-			Documentation/kdump/kdump.txt for further details.
-
-	crashkernel=range1:size1[,range2:size2,...][@offset]
-			[KNL] Same as above, but depends on the memory
-			in the running system. The syntax of range is
-			start-[end] where start and end are both
-			a memory unit (amount[KMG]). See also
-			Documentation/kdump/kdump.txt for an example.
-
-	crashkernel=size[KMG],high
-			[KNL, x86_64] range could be above 4G. Allow kernel
-			to allocate physical memory region from top, so could
-			be above 4G if system have more than 4G ram installed.
-			Otherwise memory region will be allocated below 4G, if
-			available.
-			It will be ignored if crashkernel=X is specified.
-	crashkernel=size[KMG],low
-			[KNL, x86_64] range under 4G. When crashkernel=X,high
-			is passed, kernel could allocate physical memory region
-			above 4G, that cause second kernel crash on system
-			that require some amount of low memory, e.g. swiotlb
-			requires at least 64M+32K low memory, also enough extra
-			low memory is needed to make sure DMA buffers for 32-bit
-			devices won't run out. Kernel would try to allocate at
-			at least 256M below 4G automatically.
-			This one let user to specify own low range under 4G
-			for second kernel instead.
-			0: to disable low allocation.
-			It will be ignored when crashkernel=X,high is not used
-			or memory reserved is below 4G.

-
-	debug_guardpage_minorder=
-			[KNL] When CONFIG_DEBUG_PAGEALLOC is set, this
-			parameter allows control of the order of pages that will
-			be intentionally kept free (and hence protected) by the
-			buddy allocator. Bigger value increase the probability
-			of catching random memory corruption, but reduce the
-			amount of memory for normal system use. The maximum
-			possible value is MAX_ORDER/2.  Setting this parameter
-			to 1 or 2 should be enough to identify most random
-			memory corruption problems caused by bugs in kernel or
-			driver code when a CPU writes to (or reads from) a
-			random memory location. Note that there exists a class
-			of memory corruptions problems caused by buggy H/W or
-			F/W or by drivers badly programing DMA (basically when
-			memory is written at bus level and the CPU MMU is
-			bypassed) which are not detectable by
-			CONFIG_DEBUG_PAGEALLOC, hence this option will not help
-			tracking down these problems.
-
-	debug_pagealloc=
-			[KNL] When CONFIG_DEBUG_PAGEALLOC is set, this
-			parameter enables the feature at boot time. In
-			default, it is disabled. We can avoid allocating huge

-
-	disable_mtrr_trim [X86, Intel and AMD only]
-			By default the kernel will trim any uncacheable

-
-	dma_debug_entries=<number>
-			This option allows to tune the number of preallocated
-			entries for DMA-API debugging code. One entry is
-			required per DMA-API allocation. Use this if the
-			DMA-API debugging code disables itself because the
-			architectural default is too low.
-
-	dma_debug_driver=<driver_name>
-			With this option the DMA-API debugging driver
-			filter feature can be enabled at boot time. Just
-			pass the driver to filter for as the parameter.

-
-	drm_kms_helper.edid_firmware=[<connector>:]<file>[,[<connector>:]<file>]
-			Broken monitors, graphic adapters, KVMs and EDIDless
-			panels may send no or incorrect EDID data sets.
-			This parameter allows to specify an EDID data sets

-			edid/1680x1050.bin, or edid/1920x1080.bin is given
-			and no file with the same name exists. Details and

-			available in Documentation/EDID/HOWTO.txt. An EDID
-			data set will only be used for a particular connector,
-			if its name and a colon are prepended to the EDID

-			set the brightness of the panel backlight. Normally a
-			brightness value of 0 indicates backlight switched off,
-			and the maximum of the brightness value sets the backlight
-			to maximum brightness. If this parameter is set to 0
-			(default) and the machine requires it, or this parameter

-
-	ide-generic.probe-mask= [HW] (E)IDE subsystem
-			Format: <int>
-			Probe mask for legacy ISA IDE ports.  Depending on
-			platform up to 6 ports are supported, enabled by
-			setting corresponding bits in the mask to 1.  The
-			default value is 0x0, which has a special meaning.
-			On systems that have PCI, it triggers scanning the
-			PCI bus for the first and the second port, which
-			are then probed.  On systems without PCI the value
-			of 0x0 enables probing the two first ports as if it
-			was 0x3.
-
-	ide-pci-generic.all-generic-ide [HW] (E)IDE subsystem
-			Claim all unknown PCI IDE storage controllers.
-
-	idle=		[X86]
-			Format: idle=poll, idle=halt, idle=nomwait

-			the FPU and the NaN encoding requested with the value
-			of an ELF file header flag individually set by each
-			binary.  Hardware implementations are permitted to
-			support either or both of the legacy and the 2008 NaN
-			encoding mode.
-
-			Available settings are as follows:
-			strict	accept binaries that request a NaN encoding
-				supported by the FPU
-			legacy	only accept legacy-NaN binaries, if supported
-				by the FPU
-			2008	only accept 2008-NaN binaries, if supported
-				by the FPU
-			relaxed	accept any binaries regardless of whether
-				supported by the FPU
-
-			The FPU emulator is always able to support both NaN
-			encodings, so if no FPU hardware is present or it has
-			been disabled with 'nofpu', then the settings of
-			'legacy' and '2008' strap the emulator accordingly,
-			'relaxed' straps the emulator for both legacy-NaN and
-			2008-NaN, whereas 'strict' enables legacy-NaN only on
-			legacy processors and both NaN encodings on MIPS32 or
-			MIPS64 CPUs.
-
-			The setting for ABS.fmt/NEG.fmt instruction execution
-			mode generally follows that for the NaN encoding,
-			except where unsupported by hardware.
-

-			Format: "tcb"
-
-	ima_tcb		[IMA] Deprecated.  Use ima_policy= instead.

-		off
-			Disable intel iommu driver.
-		igfx_off [Default Off]
-			By default, gfx is mapped as normal device. If a gfx
-			device has a dedicated DMAR unit, the DMAR unit is
-			bypassed by not enabling DMAR with this option. In
-			this case, gfx device will use physical address for
-			DMA.
-		forcedac [x86_64]
-			With this option iommu will not optimize to look
-			for io virtual address below 32-bit forcing dual
-			address cycle on pci bus for cards supporting greater
-			than 32-bit addressing. The default is to look
-			for translation below 32-bit and if not available

-		         scaling driver for the supported processors
-		       force
-			 Enable intel_pstate on systems that prohibit it by default
-			 in favor of acpi-cpufreq. Forcing the intel_pstate driver
-			 instead of acpi-cpufreq may disable platform features, such
-			 as thermal controls and power capping, that rely on ACPI
-			 P-States information being indicated to OSPM and therefore
-			 should be used with caution. This option does not work with
-			 processors that aren't supported by the intel_pstate driver
-			 or on platforms that use pcc-cpufreq instead of acpi-cpufreq.
-		       no_hwp
-		         Do not enable hardware P state control (HWP)

-
-	isolcpus=	[KNL,SMP] Isolate CPUs from the general scheduler.
-			The argument is a cpu list, as described above.
-
-			This option can be used to specify one or more CPUs
-			to isolate from the general SMP balancing and scheduling
-			algorithms. You can move a process onto or off an
-			"isolated" CPU via the CPU affinity syscalls or cpuset.
-			<cpu number> begins at 0 and the maximum value is
-			"number of CPUs in system - 1".
-
-			This option is the preferred way to isolate CPUs. The
-			alternative -- manually setting the CPU mask of all
-			tasks in the system -- can cause problems and
-			suboptimal load balancer performance.

-
-	kernelcore=	[KNL,X86,IA-64,PPC]
-			Format: nn[KMGTPE] | "mirror"
-			This parameter
-			specifies the amount of memory usable by the kernel
-			for non-movable allocations.  The requested amount is
-			spread evenly throughout all nodes in the system. The
-			remaining memory in each node is used for Movable
-			pages. In the event, a node is too small to have both
-			kernelcore and Movable pages, kernelcore pages will
-			take priority and other nodes will have a larger number
-			of Movable pages.  The Movable zone is used for the
-			allocation of pages that may be reclaimed or moved
-			by the page migration subsystem.  This means that
-			HugeTLB pages may not be allocated from this zone.
-			Note that allocations like PTEs-from-HighMem still
-			use the HighMem zone if it exists, and the Normal
-			zone if it does not.
-
-			Instead of specifying the amount of memory (nn[KMGTPE]),
-			you can specify "mirror" option. In case "mirror"
-			option is specified, mirrored (reliable) memory is used
-			for non-movable allocations and remaining memory is used
-			for Movable pages. nn[KMGTPE] and "mirror" are exclusive,
-			so you can NOT specify nn[KMGTPE] and "mirror" at the same
-			time.
-

-			optional and is the number seconds in between
-			each poll cycle to the debug port in case you need
-			the functionality for interrupting the kernel with
-			gdb or control-c on the dbgp connection.  When
-			not using this parameter you use sysrq-g to break into
-			the kernel debugger.
-
-	kgdboc=		[KGDB,HW] kgdb over consoles.

-			libata.dma=1	  PATA and SATA Disk DMA only
-			libata.dma=2	  ATAPI (CDROM) DMA only
-			libata.dma=4	  Compact Flash DMA only
-			Combinations also work, so libata.dma=3 enables DMA
-			for disks and CDROMs, but not CFs.
-
-	libata.ignore_hpa=	[LIBATA] Ignore HPA limit
-			libata.ignore_hpa=0	  keep BIOS limits (default)
-			libata.ignore_hpa=1	  ignore limits, using full disk
-
-	libata.noacpi	[LIBATA] Disables use of ACPI in libata suspend/resume
-			when set.
-			Format: <int>
-
-	libata.force=	[LIBATA] Force configurations.  The format is comma
-			separated list of "[ID:]VAL" where ID is
-			PORT[.DEVICE].  PORT and DEVICE are decimal numbers
-			matching port, link or device.  Basically, it matches
-			the ATA ID string printed on console by libata.  If
-			the whole ID part is omitted, the last PORT and DEVICE
-			values are used.  If ID hasn't been specified yet, the
-			configuration applies to all ports, links and devices.
-
-			If only DEVICE is omitted, the parameter applies to
-			the port and all links and devices behind it.  DEVICE
-			number of 0 either selects the first device or the
-			first fan-out link behind PMP device.  It does not
-			select the host link.  DEVICE number of 15 selects the
-			host link and device attached to it.
-
-			The VAL specifies the configuration to force.  As long
-			as there's no ambiguity shortcut notation is allowed.
-			For example, both 1.5 and 1.5G would work for 1.5Gbps.
-			The following configurations can be forced.
-
-			* Cable type: 40c, 80c, short40c, unk, ign or sata.
-			  Any ID with matching PORT is used.
-
-			* SATA link speed limit: 1.5Gbps or 3.0Gbps.
-
-			* Transfer mode: pio[0-7], mwdma[0-4] and udma[0-7].
-			  udma[/][16,25,33,44,66,100,133] notation is also
-			  allowed.
-
-			* [no]ncq: Turn on or off NCQ.
-
-			* [no]ncqtrim: Turn off queued DSM TRIM.
-
-			* nohrst, nosrst, norst: suppress hard, soft

-
-			* rstonce: only attempt one reset during
-			  hot-unplug link recovery
-
-			* dump_id: dump IDENTIFY data.
-
-			* atapi_dmadir: Enable ATAPI DMADIR bridge support
-

-
-	locktorture.onoff_holdoff= [KNL]
-			Set time (s) after boot for CPU-hotplug testing.
-
-	locktorture.onoff_interval= [KNL]
-			Set time (s) between CPU-hotplug operations, or
-			zero to disable CPU-hotplug testing.
-
-	locktorture.shuffle_interval= [KNL]
-			Set task-shuffle interval (jiffies).  Shuffling
-			tasks allows some CPUs to go into dyntick-idle
-			mode during the locktorture test.
-
-	locktorture.shutdown_secs= [KNL]
-			Set time (s) after boot system shutdown.  This
-			is useful for hands-off automated testing.

-			Time (s) between statistics printk()s.
-
-	locktorture.stutter= [KNL]
-			Time (s) to stutter testing, for example,

-	logibm.irq=	[HW,MOUSE] Logitech Bus Mouse Driver
-			Format: <irq>
-
-	loglevel=	All Kernel Messages with a loglevel smaller than the
-			console loglevel will be printed to the console. It can
-			also be changed with klogd or other programs. The
-			loglevels are defined as follows:
-
-			0 (KERN_EMERG)		system is unusable
-			1 (KERN_ALERT)		action must be taken immediately
-			2 (KERN_CRIT)		critical conditions
-			3 (KERN_ERR)		error conditions
-			4 (KERN_WARNING)	warning conditions
-			5 (KERN_NOTICE)		normal but significant condition
-			6 (KERN_INFO)		informational
-			7 (KERN_DEBUG)		debug-level messages
-
-	log_buf_len=n[KMG]	Sets the size of the printk ring buffer,
-			in bytes.  n must be a power of two and greater
-			than the minimal size. The minimal size is defined
-			by LOG_BUF_SHIFT kernel config parameter. There is
-			also CONFIG_LOG_CPU_MAX_BUF_SHIFT config parameter
-			that allows to increase the default size depending on
-			the number of CPUs. See init/Kconfig for more details.
-
-	logo.nologo	[FB] Disables display of the built-in Linux logo.
-			This may be used to provide more screen space for
-			kernel log messages and is useful when debugging
-			kernel boot problems.
-
-	lp=0		[LP]	Specify parallel ports to use, e.g,
-	lp=port[,port...]	lp=none,parport0 (lp0 not configured, lp1 uses
-	lp=reset		first parallel port). 'lp=0' disables the
-	lp=auto			printer driver. 'lp=reset' (which can be
-				specified in addition to the ports) causes
-				attached printers to be reset. Using
-				lp=port1,port2,... specifies the parallel ports
-				to associate lp devices with, starting with
-				lp0. A port specification may be 'none' to skip
-				that lp device, or a parport name such as
-				'parport0'. Specifying 'lp=auto' instead of a
-				port specification list means that device IDs
-				from each port should be examined, to see if
-				an IEEE 1284-compliant printer is attached; if
-				so, the driver will manage that printer.
-				See also header of drivers/char/lp.c.
-
-	lpj=n		[KNL]
-			Sets loops_per_jiffy to given constant, thus avoiding
-			time-consuming boot-time autodetection (up to 250 ms per
-			CPU). 0 enables autodetection (default). To determine
-			the correct value for your kernel, boot with normal
-			autodetection and see what value is printed. Note that
-			on SMP systems the preset will be applied to all CPUs,
-			which is likely to cause problems if your CPUs need
-			significantly divergent settings. An incorrect value
-			will cause delays in the kernel to be wrong, leading to
-			unpredictable I/O errors and other breakage. Although
-			unlikely, in the extreme case this might damage your
-			hardware.
-
-	ltpc=		[NET]
-			Format: <io>,<irq>,<dma>

-
-	machtype=	[Loongson] Share the same kernel image file between different
-			 yeeloong laptop.
-			Example: machtype=lemote-yeeloong-2f-7inch
-
-	max_addr=nn[KMG]	[KNL,BOOT,ia64] All physical memory greater
-			than or equal to this physical address is ignored.
-
-	maxcpus=	[SMP] Maximum number of processors that	an SMP kernel
-			will bring up during bootup.  maxcpus=n : n >= 0 limits
-			the kernel to bring up 'n' processors. Surely after
-			bootup you can bring up the other plugged cpu by executing
-			"echo 1 > /sys/devices/system/cpu/cpuX/online". So maxcpus
-			only takes effect during system bootup.
-			While n=0 is a special case, it is equivalent to "nosmp",
-			which also disables the IO APIC.
-
-	max_loop=	[LOOP] The number of loop block devices that get
-	(loop.max_loop)	unconditionally pre-created at init time. The default
-			number is configured by BLK_DEV_LOOP_MIN_COUNT. Instead
-			of statically allocating a predefined number, loop
-			devices can be requested on-demand with the
-			/dev/loop-control interface.

-	mem=nn[KMG]	[KNL,BOOT] Force usage of a specific amount of memory
-			Amount of memory to be used when the kernel is not able
-			to see the whole system memory or for test.
-			[X86] Work as limiting max address. Use together
-			with memmap= to avoid physical address space collisions.
-			Without memmap= PCI devices could be placed at addresses
-			belonging to unused RAM.
-
-	mem=nopentium	[BUGS=X86-32] Disable usage of 4MB pages for kernel
-			memory.
-
-	memchunk=nn[KMG]

-			per-device physically contiguous DMA buffers.
-
-        memhp_default_state=online/offline
-			[KNL] Set the initial state for the memory hotplug
-			onlining policy. If not specified, the default value is
-			set according to the
-			CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE kernel config
-			option.
-			See Documentation/memory-hotplug.txt.
-
-	memmap=exactmap	[KNL,X86] Enable setting of an exact

-
-	memmap=nn[KMG]@ss[KMG]
-			[KNL] Force usage of a specific region of memory.
-			Region of memory to be used is from ss to ss+nn.

-			Region of memory to be marked is from ss to ss+nn.
-
-	memmap=nn[KMG]$ss[KMG]
-			[KNL,ACPI] Mark specific memory as reserved.
-			Region of memory to be reserved is from ss to ss+nn.
-			Example: Exclude memory from 0x18690000-0x1869ffff
-			         memmap=64K$0x18690000
-			         or
-			         memmap=0x10000$0x18690000
-
-	memmap=nn[KMG]!ss[KMG]
-			[KNL,X86] Mark specific memory as protected.
-			Region of memory to be used, from ss to ss+nn.
-			The memory region may be marked as e820 type 12 (0xc)
-			and is NVDIMM or ADR memory.
-
-	memory_corruption_check=0/1 [X86]
-			Some BIOSes seem to corrupt the first 64k of
-			memory when doing things like suspend/resume.
-			Setting this option will scan the memory
-			looking for corruption.  Enabling this will
-			both detect corruption and prevent the kernel
-			from using the memory being corrupted.
-			However, its intended as a diagnostic tool; if
-			repeatable BIOS-originated corruption always
-			affects the same memory, you can use memmap=
-			to prevent the kernel from using that memory.
-
-	memory_corruption_check_size=size [X86]
-			By default it checks for corruption in the low
-			64k, making this memory unavailable for normal
-			use.  Use this parameter to scan for
-			corruption in more or less memory.
-
-	memory_corruption_check_period=seconds [X86]
-			By default it checks for corruption every 60
-			seconds.  Use this parameter to check at some
-			other rate.  0 disables periodic checking.
-
-	memtest=	[KNL,X86,ARM] Enable memtest
-			Format: <integer>
-			default : 0 <disable>
-			Specifies the number of memtest passes to be
-			performed. Each pass selects another test
-			pattern from a given set of patterns. Memtest
-			fills the memory with this pattern, validates
-			memory contents and reserves bad memory
-			regions that are detected.
-
-	meye.*=		[HW] Set MotionEye Camera parameters
-			See Documentation/video4linux/meye.txt.
-
-	mfgpt_irq=	[IA-32] Specify the IRQ to use for the
-			Multi-Function General Purpose Timers on AMD Geode
-			platforms.
-
-	mfgptfix	[X86-32] Fix MFGPT timers on AMD Geode platforms when
-			the BIOS has incorrectly applied a workaround. TinyBIOS
-			version 0.98 is known to be affected, 0.99 fixes the
-			problem by letting the user disable the workaround.
-
-	mga=		[HW,DRM]
-
-	min_addr=nn[KMG]	[KNL,BOOT,ia64] All physical memory below this

-
-	mini2440=	[ARM,HW,KNL]
-			Format:[0..2][b][c][t]
-			Default: "0tb"
-			MINI2440 configuration specification:
-			0 - The attached screen is the 3.5" TFT
-			1 - The attached screen is the 7" TFT
-			2 - The VGA Shield is attached (1024x768)
-			Leaving out the screen size parameter will not load
-			the TFT driver, and the framebuffer will be left
-			unconfigured.
-			b - Enable backlight. The TFT backlight pin will be
-			linked to the kernel VESA blanking code and a GPIO
-			LED. This parameter is not necessary when using the
-			VGA shield.
-			c - Enable the s3c camera interface.
-			t - Reserved for enabling touchscreen support. The
-			touchscreen support is not enabled in the mainstream
-			kernel as of 2.6.30, a preliminary port can be found
-			in the "bleeding edge" mini2440 support kernel at
-			http://repo.or.cz/w/linux-2.6/mini2440.git
-
-	mminit_loglevel=
-			[KNL] When CONFIG_DEBUG_MEMORY_INIT is set, this
-			parameter allows control of the logging verbosity for
-			the additional memory initialisation checks. A value
-			of 0 disables mminit logging and a level of 4 will
-			log everything. Information is printed at KERN_DEBUG
-			so loglevel=8 may also need to be specified.
-
-	module.sig_enforce
-			[KNL] When CONFIG_MODULE_SIG is set, this means that
-			modules without (valid) signatures will fail to load.
-			Note that if CONFIG_MODULE_SIG_FORCE is set, that
-			is always true, so this option does nothing.
-
-	module_blacklist=  [KNL] Do not load a comma-separated list of
-			modules.  Useful for debugging problem modules.
-
-	mousedev.tap_time=
-			[MOUSE] Maximum time between finger touching and

-	mousedev.xres=	[MOUSE] Horizontal screen resolution, used for devices
-			reporting absolute coordinates, such as tablets
-	mousedev.yres=	[MOUSE] Vertical screen resolution, used for devices
-			reporting absolute coordinates, such as tablets
-
-	movablecore=nn[KMG]	[KNL,X86,IA-64,PPC] This parameter
-			is similar to kernelcore except it specifies the
-			amount of memory used for migratable allocations.
-			If both kernelcore and movablecore is specified,
-			then kernelcore will be at *least* the specified
-			value but may be more. If movablecore on its own
-			is specified, the administrator must be careful
-			that the amount of memory usable for all allocations
-			is not too small.
-
-	movable_node	[KNL,X86] Boot-time switch to enable the effects
-			of CONFIG_MOVABLE_NODE=y. See mm/Kconfig for details.
-
-	MTD_Partition=	[MTD]

-
-	mtrr_chunk_size=nn[KMG] [X86]
-			used for mtrr cleanup. It is largest continuous chunk
-			that could hold holes aka. UC entries.
-
-	mtrr_gran_size=nn[KMG] [X86]
-			Used for mtrr cleanup. It is granularity of mtrr block.
-			Default is 1.
-			Large value could prevent small alignment from
-			using up MTRRs.
-
-	mtrr_spare_reg_nr=n [X86]
-			Format: <integer>
-			Range: 0,7 : spare reg number
-			Default : 1
-			Used for mtrr cleanup. It is spare mtrr entries number.
-			Set to 2 or more if your graphical card needs more.

-
-	netdev=		[NET] Network devices parameters
-			Format: <irq>,<io>,<mem_start>,<mem_end>,<name>

-
-	nf_conntrack.acct=
-			[NETFILTER] Enable connection tracking flow accounting
-			0 to disable accounting

-
-	nfs.callback_nr_threads=
-			[NFSv4] set the total number of threads that the
-			NFS client will assign to service NFSv4 callback
-			requests.
-
-	nfs.callback_tcpport=
-			[NFS] set the TCP port on which the NFSv4 callback
-			channel should listen.
-
-	nfs.cache_getent=
-			[NFS] sets the pathname to the program which is used
-			to update the NFS client cache entries.
-
-	nfs.cache_getent_timeout=
-			[NFS] sets the timeout after which an attempt to
-			update a cache entry is deemed to have failed.
-
-	nfs.idmap_cache_timeout=
-			[NFS] set the maximum lifetime for idmapper cache
-			entries.
-
-	nfs.enable_ino64=
-			[NFS] enable 64-bit inode numbers.
-			If zero, the NFS client will fake up a 32-bit inode
-			number for the readdir() and stat() syscalls instead
-			of returning the full 64-bit number.
-			The default is to return 64-bit inode numbers.
-
-	nfs.max_session_cb_slots=
-			[NFSv4.1] Sets the maximum number of session
-			slots the client will assign to the callback
-			channel. This determines the maximum number of
-			callbacks the client will process in parallel for
-			a particular server.
-
-	nfs.max_session_slots=
-			[NFSv4.1] Sets the maximum number of session slots
-			the client will attempt to negotiate with the server.
-			This limits the number of simultaneous RPC requests
-			that the client can send to the NFSv4.1 server.
-			Note that there is little point in setting this
-			value higher than the max_tcp_slot_table_limit.
-
-	nfs.nfs4_disable_idmapping=
-			[NFSv4] When set to the default of '1', this option
-			ensures that both the RPC level authentication
-			scheme and the NFS level operations agree to use
-			numeric uids/gids if the mount is using the
-			'sec=sys' security flavour. In effect it is
-			disabling idmapping, which can make migration from
-			legacy NFSv2/v3 systems to NFSv4 easier.
-			Servers that do not support this mode of operation
-			will be autodetected by the client, and it will fall
-			back to using the idmapper.
-			To turn off this behaviour, set the value to '0'.
-	nfs.nfs4_unique_id=
-			[NFS4] Specify an additional fixed unique ident-
-			ification string that NFSv4 clients can insert into
-			their nfs_client_id4 string.  This is typically a
-			UUID that is generated at system install time.
-
-	nfs.send_implementation_id =
-			[NFSv4.1] Send client implementation identification
-			information in exchange_id requests.
-			If zero, no implementation identification information
-			will be sent.
-			The default is to send the implementation identification
-			information.
-
-	nfs.recover_lost_locks =
-			[NFSv4] Attempt to recover locks that were lost due
-			to a lease timeout on the server. Please note that
-			doing this risks data corruption, since there are
-			no guarantees that the file will remain unchanged
-			after the locks are lost.
-			If you want to enable the kernel legacy behaviour of
-			attempting to recover these locks, then set this
-			parameter to '1'.
-			The default parameter value of '0' causes the kernel
-			not to attempt recovery of lost locks.
-
-	nfs4.layoutstats_timer =
-			[NFSv4.2] Change the rate at which the kernel sends
-			layoutstats to the pNFS metadata server.
-
-			Setting this to value to 0 causes the kernel to use
-			whatever value is the default set by the layout
-			driver. A non-zero value sets the minimum interval
-			in seconds between layoutstats transmissions.
-
-	nfsd.nfs4_disable_idmapping=
-			[NFSv4] When set to the default of '1', the NFSv4
-			server will return only numeric uids and gids to
-			clients using auth_sys, and will accept numeric uids
-			and gids from such clients.  This is intended to ease
-			migration from NFSv2/v3.
-
-	objlayoutdriver.osd_login_prog=
-			[NFS] [OBJLAYOUT] sets the pathname to the program which
-			is used to automatically discover and login into new
-			osd-targets. Please see:
-			Documentation/filesystems/pnfs.txt for more explanations
-
-	nmi_debug=	[KNL,AVR32,SH] Specify one or more actions to take

-
-	nmi_watchdog=	[KNL,BUGS=X86] Debugging features for SMP kernels
-			Format: [panic,][nopanic,][num]
-			Valid num: 0 or 1
-			0 - turn hardlockup detector in nmi_watchdog off
-			1 - turn hardlockup detector in nmi_watchdog on
-			When panic is specified, panic when an NMI watchdog
-			timeout occurs (or 'nopanic' to override the opposite
-			default). To disable both hard and soft lockup detectors,
-			please see 'nowatchdog'.
-			This is useful when you use a panic=... timeout and
-			need the box quickly up again.
-
-	netpoll.carrier_timeout=
-			[NET] Specifies amount of time (in seconds) that
-			netpoll should wait for a carrier. By default netpoll
-			waits 4 seconds.
-
-	no387		[BUGS=X86-32] Tells the kernel to use the 387 maths
-			emulation library even if a 387 maths coprocessor
-			is present.
-
-	no_console_suspend
-			[HW] Never suspend the console
-			Disable suspending of consoles during suspend and
-			hibernate operations.  Once disabled, debugging
-			messages can reach various consoles while the rest
-			of the system is being put to sleep (ie, while
-			debugging driver suspend/resume hooks).  This may
-			not work reliably with all consoles, but is known
-			to work with serial and VGA consoles.
-			To facilitate more flexible debugging, we also add
-			console_suspend, a printk module parameter to control
-			it. Users could use console_suspend (usually
-			/sys/module/printk/parameters/console_suspend) to
-			turn on/off it dynamically.
-
-	noaliencache	[MM, NUMA, SLAB] Disables the allocation of alien
-			caches in the slab allocator.  Saves per-node memory,
-			but will impact performance.
-
-	noalign		[KNL,ARM]
-
-	noapic		[SMP,APIC] Tells the kernel to not make use of any
-			IOAPICs that may be present in the system.
-

-			and restore using xsave. The kernel will fallback to
-			enabling legacy floating-point and sse state.
-
-	noxsaveopt	[X86] Disables xsaveopt used in saving x86 extended
-			register states. The kernel will fall back to use
-			xsave to save the states. By using this parameter,
-			performance of saving the states is degraded because

-	cpu0_hotplug	[X86] Turn on CPU0 hotplug feature when
-			CONFIG_BOOTPARAM_HOTPLUG_CPU0 is off.
-			Some features depend on CPU0. Known dependencies are:
-			1. Resume from suspend/hibernate depends on CPU0.
-			Suspend/hibernate will fail if CPU0 is offline and you
-			need to online CPU0 before suspend/hibernate.
-			2. PIC interrupts also depend on CPU0. CPU0 can't be
-			removed if a PIC interrupt is detected.
-			It's said poweroff/reboot may depend on CPU0 on some
-			machines although I haven't seen such issues so far
-			after CPU0 is offline on a few tested machines.
-			If the dependencies are under your control, you can
-			turn on cpu0_hotplug.
-
-	nptcg=		[IA-64] Override max number of concurrent global TLB
-			purges which is reported from either PAL_VM_SUMMARY or
-			SAL PALO.
-
-	nr_cpus=	[SMP] Maximum number of processors that	an SMP kernel
-			could support.  nr_cpus=n : n >= 1 limits the kernel to
-			support 'n' processors. It could be larger than the
-			number of already plugged CPU during bootup, later in
-			runtime you can physically add extra cpu until it reaches
-			n. So during boot up some boot time memory for per-cpu
-			variables need be pre-allocated for later physical cpu
-			hot plugging.
-
-	nr_uarts=	[SERIAL] maximum number of UARTs to be registered.
-
-	numa_balancing=	[KNL,X86] Enable or disable automatic NUMA balancing.

-			See Documentation/debugging-via-ohci1394.txt for more
-			info.
-
-	olpc_ec_timeout= [OLPC] ms delay when issuing EC commands
-			Rather than timing out after 20 ms if an EC
-			command is not properly ACKed, override the length
-			of the timeout.  We have interrupts disabled while
-			waiting for the ACK, so if this is set too high
-			interrupts *may* be lost!
-
-	omap_mux=	[OMAP] Override bootloader pin multiplexing.
-			Format: <mux_mode0.mode_name=value>...
-			For example, to override I2C bus2:

-				perfmon on Intel CPUs instead of the
-				CPU specific event set.
-			timer: [X86] Force use of architectural NMI
-				timer mode (see also oprofile.timer
-				for generic hr timer mode)
-
-	oops=panic	Always panic on oopses. Default is to just kill the
-			process, but there is a small probability of
-			deadlocking the machine.
-			This will also cause panics on machine check exceptions.
-			Useful together with panic=30 to trigger a reboot.
-
-	OSS		[HW,OSS]
-			See Documentation/sound/oss/oss-parameters.txt
-
-	page_owner=	[KNL] Boot-time page_owner enabling option.

-
-	page_poison=	[KNL] Boot-time parameter changing the state of
-			poisoning on the buddy allocator.
-			off: turn off poisoning
-			on: turn on poisoning
-
-	panic=		[KNL] Kernel behaviour on panic: delay <timeout>
-			timeout > 0: seconds before rebooting
-			timeout = 0: wait forever
-			timeout < 0: reboot immediately
-			Format: <timeout>
-
-	panic_on_warn	panic() instead of WARN().  Useful to cause kdump
-			on a WARN().
-
-	crash_kexec_post_notifiers
-			Run kdump after running panic-notifiers and dumping
-			kmsg. This only for the users who doubt kdump always
-			succeeds in any situation.
-			Note that this also increases risks of kdump failure,
-			because some panic notifiers can make the crashed
-			kernel more unstable.
-
-	parkbd.port=	[HW] Parallel port number the keyboard adapter is
-			connected to, default is 0.
-			Format: <parport#>
-	parkbd.mode=	[HW] Parallel port keyboard adapter mode of operation,

-			Format: <mode>
-
-	parport=	[HW,PPT] Specify parallel ports. 0 disables.
-			Format: { 0 | auto | 0xBBB[,IRQ[,DMA]] }
-			Use 'auto' to force the driver to use any
-			IRQ/DMA settings detected (the default is to
-			ignore detected IRQ/DMA settings because of
-			possible conflicts). You can specify the base
-			address, IRQ, and DMA settings; IRQ and DMA
-			should be numbers, or 'auto' (for using detected
-			settings on that particular port), or 'nofifo'
-			(to avoid using a FIFO even if it is detected).
-			Parallel ports are assigned in the order they
-			are specified on the command line, starting
-			with parport0.
-
-	parport_init_mode=	[HW,PPT]
-			Configure VIA parallel port to operate in
-			a specific mode. This is necessary on Pegasos
-			computer where firmware has no options for setting

-	pci=option[,option...]	[PCI] various PCI subsystem options:
-		earlydump	[X86] dump PCI config space before the kernel
-			        changes anything
-		off		[X86] don't probe for the PCI bus
-		bios		[X86-32] force use of PCI BIOS, don't access
-				the hardware directly. Use this if your machine
-				has a non-standard PCI host bridge.
-		nobios		[X86-32] disallow use of PCI BIOS, only direct
-				hardware access methods are allowed. Use this
-				if you experience crashes upon bootup and you
-				suspect they are caused by the BIOS.
-		conf1		[X86] Force use of PCI Configuration Access
-				Mechanism 1 (config address in IO port 0xCF8,
-				data in IO port 0xCFC, both 32-bit).
-		conf2		[X86] Force use of PCI Configuration Access
-				Mechanism 2 (IO port 0xCF8 is an 8-bit port for
-				the function, IO port 0xCFA, also 8-bit, sets
-				bus number. The config space is then accessed
-				through ports 0xC000-0xCFFF).
-				See http://wiki.osdev.org/PCI for more info
-				on the configuration access mechanisms.
-		noaer		[PCIE] If the PCIEAER kernel config parameter is
-				enabled, this kernel boot option can be used to
-				disable the use of PCIE advanced error reporting.
-		nodomains	[PCI] Disable support for multiple PCI
-				root domains (aka PCI segments, in ACPI-speak).
-		nommconf	[X86] Disable use of MMCONFIG for PCI
-				Configuration
-		check_enable_amd_mmconf [X86] check for and enable
-				properly configured MMIO access to PCI
-				config space on AMD family 10h CPU
-		nomsi		[MSI] If the PCI_MSI kernel config parameter is
-				enabled, this kernel boot option can be used to
-				disable the use of MSI interrupts system-wide.
-		noioapicquirk	[APIC] Disable all boot interrupt quirks.
-				Safety option to keep boot IRQs enabled. This
-				should never be necessary.
-		ioapicreroute	[APIC] Enable rerouting of boot IRQs to the
-				primary IO-APIC for bridges that cannot disable
-				boot IRQs. This fixes a source of spurious IRQs
-				when the system masks IRQs.
-		noioapicreroute	[APIC] Disable workaround that uses the
-				boot IRQ equivalent of an IRQ that connects to
-				a chipset where boot IRQs cannot be disabled.
-				The opposite of ioapicreroute.
-		biosirq		[X86-32] Use PCI BIOS calls to get the interrupt
-				routing table. These calls are known to be buggy
-				on several machines and they hang the machine
-				when used, but on other computers it's the only
-				way to get the interrupt routing table. Try
-				this option if the kernel is unable to allocate
-				IRQs or discover secondary PCI buses on your
-				motherboard.
-		rom		[X86] Assign address space to expansion ROMs.
-				Use with caution as certain devices share
-				address decoders between ROMs and other
-				resources.
-		norom		[X86] Do not assign address space to
-				expansion ROMs that do not already have
-				BIOS assigned address ranges.
-		nobar		[X86] Do not assign address space to the
-				BARs that weren't assigned by the BIOS.
-		irqmask=0xMMMM	[X86] Set a bit mask of IRQs allowed to be
-				assigned automatically to PCI devices. You can
-				make the kernel exclude IRQs of your ISA cards
-				this way.
-		pirqaddr=0xAAAAA	[X86] Specify the physical address
-				of the PIRQ table (normally generated
-				by the BIOS) if it is outside the
-				F0000h-100000h range.
-		lastbus=N	[X86] Scan all buses thru bus #N. Can be
-				useful if the kernel is unable to find your
-				secondary buses and you want to tell it
-				explicitly which ones they are.
-		assign-busses	[X86] Always assign all PCI bus
-				numbers ourselves, overriding
-				whatever the firmware may have done.
-		usepirqmask	[X86] Honor the possible IRQ mask stored
-				in the BIOS $PIR table. This is needed on
-				some systems with broken BIOSes, notably
-				some HP Pavilion N5400 and Omnibook XE3
-				notebooks. This will have no effect if ACPI
-				IRQ routing is enabled.
-		noacpi		[X86] Do not use ACPI for IRQ routing
-				or for PCI scanning.
-		use_crs		[X86] Use PCI host bridge window information
-				from ACPI.  On BIOSes from 2008 or later, this
-				is enabled by default.  If you need to use this,
-				please report a bug.
-		nocrs		[X86] Ignore PCI host bridge windows from ACPI.
-			        If you need to use this, please report a bug.
-		routeirq	Do IRQ routing for all PCI devices.
-				This is normally done in pci_enable_device(),
-				so this option is a temporary workaround
-				for broken drivers that don't call it.
-		skip_isa_align	[X86] do not align io start addr, so can
-				handle more pci cards
-		noearly		[X86] Don't do any early type 1 scanning.
-				This might help on some broken boards which
-				machine check when some devices' config space
-				is read. But various workarounds are disabled
-				and some IOMMU drivers will not work.
-		bfsort		Sort PCI devices into breadth-first order.
-				This sorting is done to get a device
-				order compatible with older (<= 2.4) kernels.
-		nobfsort	Don't sort PCI devices into breadth-first order.
-		pcie_bus_tune_off	Disable PCIe MPS (Max Payload Size)
-				tuning and use the BIOS-configured MPS defaults.
-		pcie_bus_safe	Set every device's MPS to the largest value
-				supported by all devices below the root complex.
-		pcie_bus_perf	Set device MPS to the largest allowable MPS
-				based on its parent bus. Also set MRRS (Max
-				Read Request Size) to the largest supported
-				value (no larger than the MPS that the device
-				or bus can support) for best performance.
-		pcie_bus_peer2peer	Set every device's MPS to 128B, which
-				every device is guaranteed to support. This
-				configuration allows peer-to-peer DMA between
-				any pair of devices, possibly at the cost of
-				reduced performance.  This also guarantees
-				that hot-added devices will work.
-		cbiosize=nn[KMG]	The fixed amount of bus space which is
-				reserved for the CardBus bridge's IO window.
-				The default value is 256 bytes.
-		cbmemsize=nn[KMG]	The fixed amount of bus space which is

-						[:<subvendor>:<subdevice>][; ...]
-				Specifies alignment and device to reassign
-				aligned memory resources.
-				If <order of align> is not specified,
-				PAGE_SIZE is used as alignment.
-				PCI-PCI bridge can be specified, if resource
-				windows need to be expanded.
-				To specify the alignment for several
-				instances of a device, the PCI vendor,
-				device, subvendor, and subdevice may be
-				specified, e.g., 4096@pci:8086:9c22:103c:198f
-		ecrc=		Enable/disable PCIe ECRC (transaction layer
-				end-to-end CRC checking).
-				bios: Use BIOS/firmware settings. This is the
-				the default.
-				off: Turn ECRC off

-				reserved for hotplug bridge's memory window.
-				Default size is 2 megabytes.
-		hpbussize=nn	The minimum amount of additional bus numbers
-				reserved for buses below a hotplug bridge.
-				Default is 1.
-		realloc=	Enable/disable reallocating PCI bridge resources

-	pcie_ports=	[PCIE] PCIe ports handling:
-		auto	Ask the BIOS whether or not to use native PCIe services
-			associated with PCIe ports (PME, hot-plug, AER).  Use

-	rcu_nocbs=	[KNL]
-			The argument is a cpu list, as described above.
-
-			In kernels built with CONFIG_RCU_NOCB_CPU=y, set
-			the specified list of CPUs to be no-callback CPUs.
-			Invocation of these CPUs' RCU callbacks will
-			be offloaded to "rcuox/N" kthreads created for
-			that purpose, where "x" is "b" for RCU-bh, "p"
-			for RCU-preempt, and "s" for RCU-sched, and "N"
-			is the CPU number.  This reduces OS jitter on the
-			offloaded CPUs, which can be useful for HPC and
-			real-time workloads.  It can also improve energy
-			efficiency for asymmetric multiprocessors.
-
-	rcu_nocb_poll	[KNL]
-			Rather than requiring that offloaded CPUs
-			(specified by rcu_nocbs= above) explicitly
-			awaken the corresponding "rcuoN" kthreads,
-			make these kthreads poll for callbacks.
-			This improves the real-time response for the
-			offloaded CPUs by relieving them of the need to
-			wake up the corresponding kthread, but degrades
-			energy efficiency by requiring that the kthreads
-			periodically wake up to do the polling.

-
-	rcutree.gp_preinit_delay=	[KNL]
-			Set the number of jiffies to delay each step of
-			RCU grace-period pre-initialization, that is,
-			the propagation of recent CPU-hotplug changes up
-			the rcu_node combining tree.  This only has effect
-			when CONFIG_RCU_TORTURE_TEST_SLOW_PREINIT is set.
-
-	rcutree.rcu_fanout_exact= [KNL]
-			Disable autobalancing of the rcu_node combining
-			tree.  This is used by rcutorture, and might
-			possibly be useful for architectures having high
-			cache-to-cache transfer latencies.
-
-	rcutree.rcu_fanout_leaf= [KNL]
-			Change the number of CPUs assigned to each
-			leaf rcu_node structure.  Useful for very

-
-	rcutree.jiffies_till_next_fqs= [KNL]
-			Set delay between subsequent attempts to force
-			quiescent states.  Units are jiffies, minimum
-			value is one, and maximum value is HZ.
-
-	rcutree.kthread_prio= 	 [KNL,BOOT]
-			Set the SCHED_FIFO priority of the RCU per-CPU
-			kthreads (rcuc/N). This value is also used for
-			the priority of the RCU boost threads (rcub/N)
-			and for the RCU grace-period kthreads (rcu_bh,
-			rcu_preempt, and rcu_sched). If RCU_BOOST is
-			set, valid values are 1-99 and the default is 1
-			(the least-favored priority).  Otherwise, when
-			RCU_BOOST is not set, valid values are 0-99 and
-			the default is zero (non-realtime operation).
-
-	rcutree.rcu_nocb_leader_stride= [KNL]
-			Set the number of NOCB kthread groups, which
-			defaults to the square root of the number of

-			Set callbacks/threads for rcu_barrier() testing.
-
-	rcutorture.nfakewriters= [KNL]

-			test, hence the "fake".
-
-	rcutorture.nreaders= [KNL]
-			Set number of RCU readers.  The value -1 selects
-			N-1, where N is the number of CPUs.  A value

-
-	rcupdate.rcu_normal= [KNL]
-			Use only normal grace-period primitives,
-			for example, synchronize_rcu() instead of

-	sunrpc.udp_slot_table_entries=
-			[NFS,SUNRPC]
-			Sets the upper limit on the number of simultaneous

-
-	suspend.pm_test_delay=
-			[SUSPEND]
-			Sets the number of seconds to remain in a suspend test
-			mode before resuming the system (see

-			transfers pages from Xen hypervisor back to the
-			kernel based on different criteria.
-
-	topology=	[S390]
-			Format: {off | on}

-	tp720=		[HW,PS2]
-
-	tpm_suspend_pcr=[HW,TPM]
-			Format: integer pcr id
-			Specify that at suspend time, the tpm driver
-			should extend the specified pcr with zeros,
-			as a workaround for some chips which fail to
-			flush the last written pcr on TPM_SaveState.
-			This will guarantee that all the other pcrs
-			are saved.
-
-	trace_buf_size=nn[KMG]
-			[FTRACE] will set tracing buffer size on each cpu.
-
-	trace_event=[event-list]
-			[FTRACE] Set and start specified trace events in order
-			to facilitate early boot debugging. The event-list is a
-			comma separated list of trace events to enable. See
-			also Documentation/trace/events.txt
-
-	trace_options=[option-list]
-			[FTRACE] Enable or disable tracer options at boot.
-			The option-list is a comma delimited list of options
-			that can be enabled or disabled just as if you were
-			to echo the option name into
-
-			    /sys/kernel/debug/tracing/trace_options
-
-			For example, to enable stacktrace option (to dump the
-			stack trace of each event), add to the command line:

-
-			See also Documentation/trace/ftrace.txt "trace options"
-			section.
-
-	tp_printk[FTRACE]
-			Have the tracepoints sent to printk as well as the
-			tracing ring buffer. This is useful for early boot up
-			where the system hangs or reboots and does not give the
-			option for reading the tracing buffer or performing a
-			ftrace_dump_on_oops.
-
-			To turn off having tracepoints sent to printk,
-			 echo 0 > /proc/sys/kernel/tracepoint_printk
-			Note, echoing 1 into this file without the
-			tracepoint_printk kernel cmdline option has no effect.
-
-			** CAUTION **
-
-			Having tracepoints sent to printk() and activating high
-			frequency tracepoints such as irq or sched, can cause
-			the system to live lock.
-
-	traceoff_on_warning
-			[FTRACE] enable this option to disable tracing when a
-			warning is hit. This turns off "tracing_on". Tracing can
-			be enabled again by echoing '1' into the "tracing_on"
-			file located in /sys/kernel/debug/tracing/
-
-			This option is useful, as it disables the trace before
-			the WARNING dump is called, which prevents the trace to
-			be filled with content caused by the warning output.
-
-			This option can also be set at run time via the sysctl
-			option:  kernel/traceoff_on_warning
-
-	transparent_hugepage=
-			[KNL]
-			Format: [always|madvise|never]
-			Can be used to control the default behavior of the system
-			with respect to transparent hugepages.
-			See Documentation/vm/transhuge.txt for more details.
-
-	tsc=		Disable clocksource stability checks for TSC.
-			Format: <string>
-			[x86] reliable: mark tsc clocksource as reliable, this
-			disables clocksource verification at runtime, as well
-			as the stability checks done at bootup.	Used to enable
-			high-resolution timer mode on older hardware, and in
-			virtualized environment.
-			[x86] noirqtime: Do not use TSC to do irq accounting.
-			Used to run time disable IRQ_TIME_ACCOUNTING on any
-			platforms where RDTSC is slow and this accounting
-			can add overhead.
-
-	turbografx.map[2|3]=	[HW,JOY]
-			TurboGraFX parallel port interface

-			Set number of hash buckets for UDP/UDP-Lite connections
-
-	uhci-hcd.ignore_oc=
-			[USB] Ignore overcurrent events (default N).

-
-	usb-storage.quirks=
-			[UMS] A list of quirks entries to supplement or
-			override the built-in unusual_devs list.  List
-			entries are separated by commas.  Each entry has
-			the form VID:PID:Flags where VID and PID are Vendor
-			and Product ID values (4-digit hex numbers) and
-			Flags is a set of characters, each corresponding

-			See the help text for CONFIG_COMPAT_VDSO for more
-			details.  If CONFIG_COMPAT_VDSO is set, the default is
-			vdso32=0; otherwise, the default is vdso32=1.
-
-			For compatibility with older kernels, vdso32=2 is an
-			alias for vdso32=0.
-
-			Try vdso32=0 if you encounter an error that says:
-			dl_main: Assertion `(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso' failed!
-
-	vector=		[IA-64,SMP]
-			vector=percpu: enable percpu vector domain
-
-	video=		[FB] Frame buffer configuration
-			See Documentation/fb/modedb.txt.
-
-	video.brightness_switch_enabled= [0,1]
-			If set to 1, on receiving an ACPI notify event

-
-	vga=		[BOOT,X86-32] Select a particular video mode
-			See Documentation/x86/boot.txt and
-			Documentation/svga.txt.
-			Use vga=ask for menu.
-			This is actually a boot loader parameter; the value is
-			passed to the kernel using a special protocol.
-
-	vmalloc=nn[KMG]	[KNL,BOOT] Forces the vmalloc area to have an exact
-			size of <nn>. This can be used to increase the

-	vsyscall=	[X86-64]
-			Controls the behavior of vsyscalls (i.e. calls to
-			fixed addresses of 0xffffffffff600x00 from legacy
-			code).  Most statically-linked binaries and older
-			versions of glibc use these calls.  Because these
-			functions are at fixed addresses, they make nice
-			targets for exploits that can control RIP.
-
-			emulate     [default] Vsyscalls turn into traps and are
-			            emulated reasonably safely.
-
-			native      Vsyscalls are native syscall instructions.
-			            This is a little bit faster than trapping
-			            and makes a few dynamic recompilers work
-			            better than they would in emulation mode.
-			            It also makes exploits much easier to write.
-
-			none        Vsyscalls don't work at all.  This makes
-			            them quite hard to use for exploits but
-			            might break your system.

-
-	vt.default_blu=	[VT]
-			Format: <blue0>,<blue1>,<blue2>,...,<blue15>

-			newly opened terminals.
-
-	vt.global_cursor_default=
-			[VT]
-			Format=<-1|0|1>
-			Set system-wide default for whether a cursor
-			is shown on new VTs. Default is -1,

-			cursors, 1 will display them.
-
-	vt.italic=	[VT] Default color for italic text; 0-15.
-			Default: 2 = green.
-
-	vt.underline=	[VT] Default color for underlined text; 0-15.

-
-	watchdog timers	[HW,WDT] For information on watchdog timers,
-			see Documentation/watchdog/watchdog-parameters.txt
-			or other driver-specific files in the
-			Documentation/watchdog/ directory.
-
-	workqueue.watchdog_thresh=
-			If CONFIG_WQ_WATCHDOG is configured, workqueue can
-			warn stall conditions and dump internal state to
-			help debugging.  0 disables workqueue stall
-			detection; otherwise, it's the stall threshold
-			duration in seconds.  The default value is 30 and
-			it can be updated at runtime by writing to the
-			corresponding sysfs file.
-
-	workqueue.disable_numa
-			By default, all work items queued to unbound
-			workqueues are affine to the NUMA nodes they're
-			issued on, which results in better behavior in
-			general.  If NUMA affinity needs to be disabled for
-			whatever reason, this option can be used.  Note
-			that this also can be controlled per-workqueue for
-			workqueues visible under /sys/bus/workqueue/.
-
-	workqueue.power_efficient
-			Per-cpu workqueues are generally preferred because
-			they show better performance thanks to cache
-			locality; unfortunately, per-cpu workqueues tend to
-			be more power hungry than unbound workqueues.
-
-			Enabling this makes the per-cpu workqueues which
-			were observed to contribute significantly to power
-			consumption unbound, leading to measurably lower
-			power usage at the cost of small performance
-			overhead.
-
-			The default value of this parameter is determined by
-			the config option CONFIG_WQ_POWER_EFFICIENT_DEFAULT.
-
-	workqueue.debug_force_rr_cpu
-			Workqueue used to implicitly guarantee that work
-			items queued without explicit CPU specified are put
-			on the local CPU.  This guarantee is no longer true
-			and while local CPU is still preferred work items
-			may be put on foreign CPUs.  This debug option
-			forces round-robin CPU selection to flush out
-			usages which depend on the now broken guarantee.
-			When enabled, memory and cache locality will be
-			impacted.
-

-			Two valid options are apbt timer only and lapic timer
-			plus one apbt timer for broadcast timer.
-			x86_intel_mid_timer=apbt_only | lapic_and_apbt
-
-	xen_512gb_limit		[KNL,X86-64,XEN]
-			Restricts the kernel running paravirtualized under Xen
-			to use only up to 512 GB of RAM. The reason to do so is
-			crash analysis tools and Xen tools for doing domain
-			save/restore/migration must be enabled to handle larger
-			domains.
-
-	xen_emul_unplug=		[HW,X86,XEN]
-			Unplug Xen emulated devices
-			Format: [unplug0,][unplug1]
-			ide-disks -- unplug primary master IDE devices
-			aux-ide-disks -- unplug non-primary-master IDE devices
-			nics -- unplug network devices
-			all -- unplug all emulated devices (NICs and IDE disks)
-			unnecessary -- unplugging emulated devices is
-				unnecessary even if the host did not respond to
-				the unplug protocol
-			never -- do not unplug even if version check succeeds
-
-	xen_nopvspin	[X86,XEN]
-			Disables the ticketlock slowpath using Xen PV
-			optimizations.
-
-	xen_nopv	[X86]
-			Disables the PV optimizations forcing the HVM guest to
-			run as generic HVM guest with no PV drivers.
-
-	xirc2ps_cs=	[NET,PCMCIA]
-			Format:
-			<irq>,<irq_mask>,<io>,<full_duplex>,<do_sound>,<lockup_hack>[,<irq2>[,<irq3>[,<irq4>]]]
