2a1fc7dc36 KVM: x86: Suppress MMIO that is triggered during task switch emulation
Explicitly suppress userspace emulated MMIO exits that are triggered when
emulating a task switch as KVM doesn't support userspace MMIO during
complex (multi-step) emulation.  Silently ignoring the exit request can
result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to
userspace for some other reason prior to purging mmio_needed.

See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write exits if
emulator detects exception") for more details on KVM's limitations with
respect to emulated MMIO during complex emulator flows.

9fe17d2ada KVM: x86/mmu: Clean up make_huge_page_split_spte() definition and intro
Tweak the definition of make_huge_page_split_spte() to eliminate an
unnecessarily long line, and opportunistically initialize child_spte to
make it more obvious that the child is directly derived from the huge
parent.

No functional change intended.

3d4415ed75 KVM: x86/mmu: Bug the VM if KVM tries to split a !hugepage SPTE
Bug the VM instead of simply warning if KVM tries to split a SPTE that is
non-present or not-huge.  KVM is guaranteed to end up in a broken state as
the callers fully expect a valid SPTE, e.g. the shadow MMU will add an
rmap entry, and all MMUs will account the expected small page.  Returning
'0' is also technically wrong now that SHADOW_NONPRESENT_VALUE exists,
i.e. would cause KVM to create a potential #VE SPTE.

While it would be possible to have the callers gracefully handle failure,
doing so would provide no practical value as the scenario really should be
impossible, while the error handling would add a non-trivial amount of
noise.

Fixes: a3fe5dbda0a4 ("KVM: x86/mmu: Split huge pages mapped by the TDP MMU when dirty logging is enabled")

Dereference auth after NULL check in tpm_buf_check_hmac_response().
Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL
dereference, when TCG_TPM2_HMAC is enabled.

3f45181358 tcp: Don't access uninit tcp_rsk(req)->ao_keyid in tcp_create_openreq_child().
syzkaller reported KMSAN splat in tcp_create_openreq_child(). [0]

The uninit variable is tcp_rsk(req)->ao_keyid.

tcp_rsk(req)->ao_keyid is initialised only when tcp_conn_request() finds
a valid TCP AO option in SYN.  Then, tcp_rsk(req)->used_tcp_ao is set
accordingly.

Let's not read tcp_rsk(req)->ao_keyid when tcp_rsk(req)->used_tcp_ao is
false.

platform/x86: asus-wmi: fix TUF laptop RGB variant
In kbd_rgb_mode_store the dev_get_drvdata() call was assuming the device
data was asus_wmi when it was actually led_classdev.

This patch corrects this by making the correct chain of calls to get the
asus_wmi driver data.

platform/x86/intel/tpmi/plr: Fix output in plr_print_bits()
Smatch complains that 'str' can be used without being initialized:

    drivers/platform/x86/intel/intel_plr_tpmi.c:178 plr_print_bits()
    error: uninitialized symbol 'str'.

In this loop, we iterate over all the set bits and print the name of the
bit.  The intention is that if there is a bit which is between 0-31 we
look for the name in the first array plr_coarse_reasons[] which has 10
elements.  If the bit is in the 32-63 range we look for it in the
plr_fine_reasons[] array which has 30 elements.  If the bit is in the
invalid ranges, 10-31 or 62-63, then we should print "UNKNOWN(%d)".

The problem is that 'str' needs to be initialized at the start of each
iteration, otherwise if we can't find the string then instead of printing
"UNKNOWN(%d)", we will re-print whatever the previous bit was.

208c6772d3 - This is basically PeterZ's idea to nest the alternative macros to avoid the
need to "spell out" the number of alternates in an ALTERNATIVE_n() macro and
   thus have an ever-increasing complexity in those definitions.
 
   For ease of bisection, the old macros are converted to the new, nested
   variants in a step-by-step manner so that in case an issue is encountered
   during testing, one can pinpoint the place where it fails easier. Because
   debugging alternatives is a serious pain.

e23dd95cfd spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
 beginnings of support for hardware initiated transfers which is itself
 independently useful for optimising fast paths in existing drivers.
 
 We also have a rework of the DMA mapping which allows finer grained
 decisions about DMA mapping messages and also helps remove some bodges
 that we'd had.
 
 Otherwise it's a fairly quiet release, a few new drivers and features
 for existing drivers, together with various cleanups and DT binding
 conversions.
 
 One regmap SPI fix made it's way in here too which I should probably
 have sent as a regmap fix instead.
 
  - Support for pre-optimising messages, reducing the overhead for
    messages that are repeatedly used (eg, reading the interrupt status
    from a device).  This will also be used for hardware initiated
    transfers in future.
  - A reworking of how DMA mapping is done, introducing a new helper and
    allowing the DMA mapping decision to be done per transfer instead of
    per message.
  - Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

b3c0eccb48 gpio updates for v6.11-rc1
GPIOLIB core:
 - rework kfifo handling rework in the character device code
 - improve the labeling of GPIOs requested as interrupts and show more info
   on interrupt-only GPIOs in debugfs
 - remove unused APIs
 - unexport interfaces that are only used from the core GPIO code
 - drop the return value from gpiochip_set_desc_names() as it cannot fail
 - move a string array definition out of a header and into a specific
   compilation unit
 - convert the last user of gpiochip_get_desc() other than GPIO core to using
   a safer alternative
 - use array_index_nospec() where applicable
 
 New drivers:
 - add a "virtual GPIO consumer" module that allows requesting GPIOs from actual
   hardware and driving tests of the in-kernel GPIO API from user-space over
   debugfs
 - add a GPIO-based "sloppy" logic analyzer module useful for "first glance"
   debugging on remote boards
 
 Driver improvements:
 - add support for a new model to gpio-pca953x
 - lock GPIOs as interrupts in gpio-sim when the lines are requested as irqs
   via the simulator domain + some other minor improvements
 - improve error reporting in gpio-syscon
 - convert gpio-ath79 to using dynamic GPIO base and range
 - use pcibios_err_to_errno() for converting PCIBIOS error codes to errno
   vaues in gpio-amd8111 and gpio-rdc321x
 - allow building gpio-brcmstb for the BCM2835 architecture
 
 DT bindings:
 - convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
 - document new properties for aspeed,gpio, fsl,qoriq-gpio and gpio-vf610
 - document new compatibles for pca953x and fsl,qoriq-gpio
 
 Documentation:
 - document stricter behavior of the GPIO character device uAPI with regards to
   reconfiguring requested line without direction set
 - clarify the effect of the active-low flag on line values and edges
 - remove documentation for the legacy GPIO API in order to stop tempting
   people to use it
 - document the preference for using pread() for reading edge events in the
   sysfs API
 
 Other:
 - add an extended initializer to the interrupt simulator allowing to specify
   a number of callbacks callers can use to be notified about irqs being
   requested and released

Merge tag 'gpio-updates-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "The majority of added lines are two new modules: the GPIO virtual
  consumer module that improves our ability to add automated tests for
  the kernel API and the "sloppy" logic analyzer module that uses the
  GPIO API to implement a coarse-grained debugging tool for useful for
  remote development.

  Other than that we have the usual assortment of various driver
  extensions, improvements to the core GPIO code, DT-bindings and other
  documentation updates as well as an extension to the interrupt
  simulator:

  GPIOLIB core:
   - rework kfifo handling rework in the character device code
   - improve the labeling of GPIOs requested as interrupts and show more
     info on interrupt-only GPIOs in debugfs
   - remove unused APIs
   - unexport interfaces that are only used from the core GPIO code
   - drop the return value from gpiochip_set_desc_names() as it cannot
     fail
   - move a string array definition out of a header and into a specific
     compilation unit
   - convert the last user of gpiochip_get_desc() other than GPIO core
     to using a safer alternative
   - use array_index_nospec() where applicable

  New drivers:
   - add a "virtual GPIO consumer" module that allows requesting GPIOs
     from actual hardware and driving tests of the in-kernel GPIO API
     from user-space over debugfs
   - add a GPIO-based "sloppy" logic analyzer module useful for "first
     glance" debugging on remote boards

  Driver improvements:
   - add support for a new model to gpio-pca953x
   - lock GPIOs as interrupts in gpio-sim when the lines are requested
     as irqs via the simulator domain + some other minor improvements
   - improve error reporting in gpio-syscon
   - convert gpio-ath79 to using dynamic GPIO base and range
   - use pcibios_err_to_errno() for converting PCIBIOS error codes to
     errno vaues in gpio-amd8111 and gpio-rdc321x
   - allow building gpio-brcmstb for the BCM2835 architecture

  DT bindings:
   - convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
   - document new properties for aspeed,gpio, fsl,qoriq-gpio and
     gpio-vf610
   - document new compatibles for pca953x and fsl,qoriq-gpio

  Documentation:
   - document stricter behavior of the GPIO character device uAPI with
     regards to reconfiguring requested line without direction set
   - clarify the effect of the active-low flag on line values and edges
   - remove documentation for the legacy GPIO API in order to stop
     tempting people to use it
   - document the preference for using pread() for reading edge events
     in the sysfs API

  Other:
   - add an extended initializer to the interrupt simulator allowing to
     specify a number of callbacks callers can use to be notified about
     irqs being requested and released"

c6e63a9882 pwm: Changes for v6.11-rc1
This contains the usual mix of fixes, cleanups, two new drivers and
 several dt binding updates. The fixes are for minor issues that are
 already old (4.11-rc1 and 3.9-rc1) and were found by code review and not
 during usage, so I didn't sent them for earlier inclusion.
 
 The changes to include/linux/mfd/stm32-timers.h and
 drivers/counter/stm32-timer-cnt.c are part of an immutable branch that
 will also be included in the mfd and counter PR. It changes some
 register definitions and affects the pwm-stm32 driver.

Pull power sequencing updates from Bartosz Golaszewski:
 "This has been in development since last year's Linux Plumbers
  Conference and was inspired by the need to enable support upstream for
  Bluetooth/WLAN chips on Qualcomm platforms.

  The main problem we're fixing is powering up devices which are
  represented as separate objects in the kernel (binding to different
  drivers) but which share parts of the power-up sequence and thus need
  some kind of a mediator who knows the possible interactions and can
  assure they don't interfere with neither device's bring up. An example
  of such an inter-driver interaction is the WCN family of BT/WLAN chips
  from Qualcomm of which some models require the user to observe a
  certain delay between driving the bt-enable and wlan-enable GPIOs.

  This is not a new problem but up to this point all attempts at
  addressing it ended up hitting one wall or another and being dropped.
  The main obstacle was the fact that most these attempts tried to
  introduce the concept of a "power sequence" into the device-tree
  bindings which breaks the main DT rule: describe the hardware, not its
  behavior. The solution I proposed focuses on making the power
  sequencer drivers interpret the actual HW description flexibly. More
  details on that are in the linked cover letter.

  The second problem fixed here is powering up PCI devices before they
  are detected on the bus. This is achieved by creating special platform
  devices for device-tree nodes describing hard-wired PCI devices which
  bind to the so-called PCI power control drivers which enable required
  resources and trigger a bus rescan once the controlled device is up
  then setup the correct devlink hierarchy for power-management.

  By combining the two new frameworks we implemented the power
  sequencing PCI power control driver which is capable of powering up
  the WLAN modules of the QCom WCN family of chipsets.

  All this has spent a significant amount of time in linux-next and
  enabled WLAN/BT support on several Qualcomm platforms. To further
  prove that this is useful and needed: right after this was picked up
  into next, I was sent a series using the subsystem for a similar
  use-case on Amlogic platforms.

  This contains the core power sequencing framework, the first driver,
  PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and
  some fixes that came later"
