At least with CONFIG_COMPILE_TEST, there's no reason to assume
that CONFIG_RESET_CONTROLLER is set, but the code for this
controller requires it since it calls device_reset().
Make CONFIG_MTK_THERMAL properly depend on CONFIG_RESET_CONTROLLER.

The commit 17e8351a7739 consistently use int for temperature,
however it missed a few in trip temperature and thermal_core.
In current codes, the trip->temperature used "unsigned long"
and zone->temperature used"int", if the temperature is negative
value, it will get wrong result when compare temperature with
trip temperature.
This patch can fix it.

req_range is declared as a u64 to cope with overflows in the
multiplication of two u32. As both req_power and power_range are u32,
we need to make sure the multiplication is done with u64 types.

Add __init attribute on a function that is only called from other __init
functions and that is not inlined, at least with gcc version 4.8.4 on an
x86 machine with allyesconfig. Currently, the function is put in the
.text.unlikely segment. Declaring it as __init will cause it to be put in
the .init.text and to disappear after initialization.
The result of objdump -x on the function before the change is as follows:
0000000000000086 l F .text.unlikely 0000000000000739 thermal_of_build_thermal_zone
And after the change it is as follows:
0000000000000000 l F .init.text 0000000000000734 thermal_of_build_thermal_zone
Done with the help of Coccinelle. The semantic patch checks for local
static non-init functions that are called from an __init function and are
not called from any other function.

Haswell and Broadwell can be configured to hash the channel
interleave function using bits [27:12] of the physical address.
On those processor models we must check to see if hashing is
enabled (bit21 of the HASWELL_HASYSDEFEATURE2 register) and
act accordingly.

eb1af3b71f9d ("Fix computation of channel address")
I switched the "sck_way" variable from holding the log2 value read
from the h/w to instead be the actual number. Unfortunately it
is needed in log2 form when used to shift the address.

Commit 2a0787051182 ("irqchip/mips-gic: Use gic_vpes instead of
NR_CPUS") & commit 78930f09b940 ("irqchip/mips-gic: Clear percpu_masks
correctly when mapping") both introduce code which accesses gic_vpes
entries in the pcpu_masks array. However, this array has length NR_CPUS.
If NR_CPUS is less than gic_vpes (ie. the kernel supports use of less
CPUs than are present in the system) then we overrun the array, clobber
some other data & generally die pretty promptly.
Most notably this affects uniprocessor kernels running on any multicore
or multithreaded Malta with a GIC (ie. the vast majority of real Malta
boards).
Fix this by only accessing up to min(gic_vpes, NR_CPUS) entries in the
pcpu_masks array, preventing the array overrun.

The emmc-phy is fully enclosed in the general register files (GRF).
Therefore as seen from the device-tree it shouldn't be a separate platform-
device but instead a sub-device of the GRF - using the simply-mfd mechanism.
The driver entered the kernel in the current merge-window, so we can still
adapt the binding without needing a fallback, as the binding hasn't been
released with a full kernel yet.

When using asynchronous read or write operations on the USB endpoints the
issuer of the IO request is notified by calling the ki_complete() callback
of the submitted kiocb when the URB has been completed.
Calling this ki_complete() callback will free kiocb. Make sure that the
structure is no longer accessed beyond that point, otherwise undefined
behaviour might occur.

When in half-duplex mode RX will be disabled before TX, but not
enabled after deactivating transmitter. This patch enables
UART_IER_RLSI and UART_IER_RDI interrupts after TX is over.

commit 21fb9f0d5e91 ("Input: twl6040-vibra - use system workqueue")
says that it switches to use the system workqueue but it did neither
- remove the workqueue struct variable
- replace code to really use the system workqueue
Instead it calls queue_work() on uninitialized info->workqueue.
The result is a NULL pointer dereference in vibra_play().
Solution: use schedule_work

The trigger delay algorithm that converts from microseconds to
the register value looks incorrect. According to most of the PMIC
documentation, the equation is
delay (Seconds) = (1 / 1024) * 2 ^ (x + 4)
except for one case where the documentation looks to have a
formatting issue and the equation looks like
delay (Seconds) = (1 / 1024) * 2 x + 4
Most likely this driver was written with the improper
documentation to begin with. According to the downstream sources
the valid delays are from 2 seconds to 1/64 second, and the
latter equation just doesn't make sense for that. Let's fix the
algorithm and the range check to match the documentation and the
downstream sources.

We shouldn't assign the parent device of the input_dev to be the
parent MFD device, because this will be used for devres which causes
input_unregister_device to run after the haptics device has been
removed, since it is itself a child of the MFD device. The default
of using the haptics device itself as the parent is correct.

This adds the VID/PID combination for the Xbox One version of the Mad
Catz FightStick TE 2.
The functionality that this provides is about on par with what the
Windows drivers for the stick manage to deliver.
What works:
- Digital stick
- 6 main buttons
- Xbox button
- The two buttons on the back
- The locking buttons (preventing accidental Xbox button press)
What doesn't work:
- Two of the main buttons (don't work on Windows either)
- The "Haptic" button setting does not have an effect (not sure if it
works on Windows)
I added the MAP_TRIGGERS_TO_BUTTONS option but in my (limited) testing
there was no practical difference with or without. The FightStick does
not have triggers though so adding it makes sense.

The gtco driver expects at least one valid endpoint. If given malicious
descriptors that specify 0 for the number of endpoints, it will crash in
the probe function. Ensure there is at least one endpoint on the interface
before using it.

pcs_parse_bits_in_pinctrl_entry uses ffs which gives bit indices
ranging from 1 to MAX. This leads to a corner case where we try to request
the pin number = MAX and fails.
bit_pos value is being calculted using ffs. pin_num_from_lsb uses
bit_pos value. pins array is populated with:
pin + pin_num_from_lsb.
The above is 1 more than usual bit indices as bit_pos uses ffs to compute
first set bit. Hence the last of the pins array is populated with the MAX
value and not MAX - 1 which causes error when we call pin_request.
mask_pos is rightly calculated as ((pcs->fmask) << (bit_pos - 1))
Consequently val_pos and submask are correct.
Hence use __ffs which gives (ffs(x) - 1) as the first bit set.

The debounce time unit for gpio_chip.set_debounce is us but
mtk_gpio_set_debounce regard it as ms.
Fix this by correct debounce time array dbnc_arr so it can find correct
debounce setting. Debounce time for first debounce setting is 500us,
correct this as well.
While I'm at it, also change the debounce time array name to
"debounce_time" for readability.

Commit da4e4f18afe0 ("drivers/perf: arm_pmu: implement CPU_PM notifier")
added code in the arm perf infrastructure that allows the kernel to
save/restore perf counters whenever the CPU enters a low-power
state. The kernel saves/restores the counters for each active event
through the armpmu_{stop/start} ARM pmu API, so that the low-power state
enter/exit cycle is emulated through pmu start/stop operations for each
event in use.
However, calling armpmu_start() for each active event on power up
executes code that requires RCU locking (perf_event_update_userpage())
to be functional, so, given that the core may call the CPU_PM notifiers
while running the idle thread in an quiescent RCU state this is not
allowed as detected through the following splat when kernel is run with
CONFIG_PROVE_LOCKING enabled:
[ 49.293286]

perf_event_update_userpage+0x0/0x260
This patch wraps the armpmu_start() call (that indirectly calls
perf_event_update_userpage()) on CPU_PM notifier power state exit (or
failed entry) within the RCU_NONIDLE() macro so that the RCU subsystem
is made aware the calling cpu is not idle from an RCU perspective for
the armpmu_start() call duration, therefore fixing the issue.

Until we get fully plumbed into of_iommu_configure, our default
IOMMU_DOMAIN_DMA domains just bypass translation. Since we achieve that
by leaving the stream table entries set to bypass instead of pointing at
a translation context, the context bank we allocate for the domain is
completely wasted. Context banks are typically a rather limited
resource, so don't hog ones we don't need.

Commit cbf8277ef456 ("iommu/arm-smmu: Treat IOMMU_DOMAIN_DMA as bypass
for now") ignores requests to attach a device to the default domain
since, without IOMMU-basked DMA ops available everywhere, the default
domain will just lead to unexpected transaction faults being reported.
Unfortunately, the way this was implemented on SMMUv2 causes a
regression with VFIO PCI device passthrough under KVM on AMD Seattle.
On this system, the host controller device is associated with both a
pci_dev *and* a platform_device, and can therefore end up with duplicate
SMR entries, resulting in a stream-match conflict at runtime.
This patch amends the original fix so that attaching to IOMMU_DOMAIN_DMA
is rejected even before configuring the SMRs. This restores the old
behaviour for now, but we'll need to look at handing host controllers
specially when we come to supporting the default domain fully.

Commit 61289cb ('iommu/amd: Remove old alias handling code')
removed the old alias handling code from the AMD IOMMU
driver because this is now handled by the IOMMU core code.
But this also removed the handling of PCI aliases, which is
not handled by the core code. This caused issues with PCI
devices that have hidden PCIe-to-PCI bridges that rewrite
the request-id.
Fix this bug by re-introducing some of the removed functions
from commit 61289cbaf6c8 and add a alias field
'struct iommu_dev_data'. This field carrys the return value
of the get_alias() function and uses that instead of the
amd_iommu_alias_table[] array in the code.

Allowing userptr bo which are basicly a list of page from some vma
(so either anonymous page or file backed page) would lead to serious
corruption of kernel structures and counters (because we overwrite
the page->mapping field when mapping buffer).
This will already block if the buffer was populated before anyone does
try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the
ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm
vm fault handler.
So to be safe just add a check to verify_access() callback.
