Pull tty/serial driver updates from Greg KH:
"Here is the "big" set of tty/serial driver changes for 6.2-rc1.
As in previous kernel releases, nothing big here at all, just some
small incremental serial/tty layer cleanups and some individual driver
additions and fixes. Highlights are:
- serial helper macros from Jiri Slaby to reduce the amount of
duplicated code in serial drivers
- api cleanups and consolidations from Ilpo Järvinen in lots of
serial drivers
- the usual set of n_gsm fixes from Daniel Starke as that code gets
exercised more
- TIOCSTI is finally able to be disabled if requested (security
hardening feature from Kees Cook)
- fsl_lpuart driver fixes and features added
- other small serial driver additions and fixes
All of these have been in linux-next for a while with no reported
problems"

'contains' applies to arrays, but 'xlnx,use-parity' is a scalar. So drop
'contains' from the 'if' schema.

These SoCs UART block are the same as JZ4725b' one, the difference is
outside of the block - it is in the clock generation unit (CGU).
The difference requires to make a quirk for early console init.

Many serial drivers do the same thing:
* send x_char if set
* keep sending from the xmit circular buffer until either
- the loop reaches the end of the xmit buffer
- TX is stopped
- HW fifo is full
* check for pending characters and:
- wake up tty writers to fill for more data into xmit buffer
- stop TX if there is nothing in the xmit buffer
The only differences are:
* how to write the character to the HW fifo
* the check of the end condition:
- is the HW fifo full?
- is limit of the written characters reached?
So unify the above into two helpers:
* uart_port_tx_limited() -- it performs the above taking the written
characters limit into account, and
* uart_port_tx() -- the same as above, except it only checks the HW
readiness, not the characters limit.
The HW specific operations (as stated as "differences" above) are passed
as arguments to the macros. They are:
* tx_ready -- returns true if HW can accept more data.
* put_char -- write a character to the device.
* tx_done -- when the write loop is done, perform arbitrary action
before potential invocation of ops->stop_tx() happens.
Note that the above are macros. This means the code is generated in
place and the above 3 arguments are "inlined". I.e. no added penalty by
generating call instructions for every single character. Nor any
indirect calls. (As in some previous versions of this patchset.)

Pull USB and Thunderbolt driver updates from Greg KH:
"Here is the large set of USB and Thunderbolt driver changes for
6.2-rc1. Overall, thanks to the removal of a driver, more lines were
removed than added, a nice change. Highlights include:
- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many
USB and other subsystem drivers, that ended up breaking the build.
That will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates

In the specification documents for the Uncompressed and MJPEG USB
Video Payloads, the field name is bmInterlaceFlags - it has been
misnamed within the kernel.
Although renaming the field does break the kernel's interface to
userspace it should be low-risk in this instance. The field is read
only and hardcoded to 0, so there was never any value in anyone
reading it. A search of the uvc-gadget application and all the
forks that I could find for it did not reveal any users either.

The Genesys Logic GL850G is a USB 2.0 Single TT hub controller that
features 4 downstream ports, an internal 5V-to-3.3V LDO regulator (can
be bypassed) and an external reset pin.
Add a device tree binding for its USB protocol part. The internal LDO is
not covered by this and can just be modelled as a fixed regulator.

When a broken USB accessory connects to a USB host, usbcore might
keep doing enumeration retries. If the host has a watchdog mechanism,
the kernel panic will happen on the host.
This patch provides an attribute early_stop to limit the numbers of retries
for each port of a hub. If a port was marked with early_stop attribute,
unsuccessful connection attempts will fail quickly. In addition, if an
early_stop port has failed to initialize, it will ignore all future
connection events until early_stop attribute is clear.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Add options to the osnoise tracer:
- 'panic_on_stop' option that panics the kernel if osnoise is
greater than some user defined threshold.
- 'preempt' option, to test noise while preemption is disabled
- 'irq' option, to test noise when interrupts are disabled
- Add .percent and .graph suffix to histograms to give different
outputs
- Add nohitcount to disable showing hitcount in histogram output
- Add new __cpumask() to trace event fields to annotate that a unsigned
long array is a cpumask to user space and should be treated as one.
- Add trace_trigger kernel command line parameter to enable trace event
triggers at boot up. Useful to trace stack traces, disable tracing
and take snapshots.
- Fix x86/kmmio mmio tracer to work with the updates to lockdep
- Unify the panic and die notifiers
- Add back ftrace_expect reference that is used to extract more
information in the ftrace_bug() code.
- Have trigger filter parsing errors show up in the tracing error log.
- Updated MAINTAINERS file to add kernel tracing mailing list and
patchwork info
- Use IDA to keep track of event type numbers.
- And minor fixes and clean ups

Allow triggers to be enabled at kernel boot up. For example:
trace_trigger="sched_switch.stacktrace if prev_state == 2"
The above will enable the stacktrace trigger on top of the sched_switch
event and only trigger if its prev_state is 2 (TASK_UNINTERRUPTIBLE). Then
at boot up, a stacktrace will trigger and be recorded in the tracing ring
buffer every time the sched_switch happens where the previous state is
TASK_INTERRUPTIBLE.
Another useful trigger would be "traceoff" which can stop tracing on an
event if a field of the event matches a certain value defined by the
filter ("if" statement).

The I2C Master Hub is a stripped down version of the GENI Serial Engine
QUP Wrapper Controller but only supporting I2C serial engines without
DMA support.
Document the I2C Serial Engine variant used within the I2C Master
Hub Wrapper.
This serial engine variant lacks DMA support, requires a core clock,
and since DMA support is lacking the memory interconnect path isn't
needed.

SoC. "renesas,riic-r9a07g043" compatible string will be used on the

SoC.
No driver changes are required as generic compatible string
"renesas,riic-rz" will be used as a fallback on RZ/Five SoC.

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.
- Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.
- Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
option, which multi-process VMMs such as crosvm rely on (see merge
commit 382b5b87a97d: "Fix a number of issues with MTE, such as
races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").
- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.
- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.
- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.
- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.
s390:
- Second batch of the lazy destroy patches
- First batch of KVM changes for kernel virtual != physical address
support
- Removal of a unused function
x86:
- Allow compiling out SMM support
- Cleanup and documentation of SMM state save area format
- Preserve interrupt shadow in SMM state save area
- Respond to generic signals during slow page faults
- Fixes and optimizations for the non-executable huge page errata
fix.
- Reprogram all performance counters on PMU filter change
- Cleanups to Hyper-V emulation and tests
- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)
- Advertise several new Intel features
- x86 Xen-for-KVM:
- Allow the Xen runstate information to cross a page boundary
- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
- Add support for 32-bit guests in SCHEDOP_poll
- Notable x86 fixes and cleanups:
- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.
- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.
- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.
- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.
- Advertise (on AMD) that the SMM_CTL MSR is not supported
- Remove unnecessary exports
Generic:
- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
Selftests:
- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.
- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.
- Introduce actual atomics for clear/set_bit() in selftests
- Add support for pinning vCPUs in dirty_log_perf_test.
- Rename the so called "perf_util" framework to "memstress".
- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.
- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.
- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).
- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.
- x86-specific selftest changes:
- Clean up x86's page table management.
- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.
- Clean up the nEPT support checks.
- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
before the test opts in via prctl().
Documentation:
- Remove deleted ioctls from documentation
- Clean up the docs for the x86 MSR filter.

Add ReST formatting to the set of userspace MSR exits/flags so that the
resulting HTML docs generate a table instead of malformed gunk. This
also fixes a warning that was introduced by a recent cleanup of the
relevant documentation (yay copy+paste).

Clean up the KVM_CAP_X86_USER_SPACE_MSR documentation to eliminate
misleading and/or inconsistent verbiage, and to actually document what
accesses are intercepted by which flags.
- s/will/may since not all #GPs are guaranteed to be intercepted
- s/deflect/intercept to align with common KVM terminology
- s/user space/userspace to align with the majority of KVM docs
- Avoid using "trap" terminology, as KVM exits to userspace _before_
stepping, i.e. doesn't exhibit trap-like behavior
- Actually document the flags

Reword the MSR filtering documentatiion to more precisely define the
behavior of filtering using common virtualization terminology.
- Explicitly document KVM's behavior when an MSR is denied
- s/handled/allowed as there is no guarantee KVM will "handle" the
MSR access
- Drop the "fall back" terminology, which incorrectly suggests that
there is existing KVM behavior to fall back to
- Fix an off-by-one error in the range (the end is exclusive)
- Call out the interaction between MSR filtering and
KVM_CAP_X86_USER_SPACE_MSR's KVM_MSR_EXIT_REASON_FILTER
- Delete the redundant paragraph on what '0' and '1' in the bitmap
means, it's covered by the sections on KVM_MSR_FILTER_{READ,WRITE}
- Delete the clause on x2APIC MSR behavior depending on APIC base, this
is covered by stating that KVM follows architectural behavior when
emulating/virtualizing MSR accesses

Delete the paragraph that describes the behavior when both
KVM_MSR_FILTER_READ | KVM_MSR_FILTER_WRITE are set for a range. There is
nothing special about KVM's handling of this combination, whereas
explicitly documenting the combination suggests that there is some magic
behavior the user needs to be aware of.
