Pull media updates from Mauro Carvalho Chehab:

 - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
   stkwebcam, tm6000, vpfe_capture and zr364xx

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

 - av7110 returned from staging/deprecated/ to staging/ as we're not
   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
   one after -rc1, giving some time to experience the API and eventually
   have changes during the next development cycle

 - New sensor drivers: imx296, imx415, ov8858

 - Atomisp had lots of changes, specially on its sensor's interface,
   making atomisp sensor drivers closer to normal sensor drivers

 - media controller kAPI has gained some helpers to traverse pipelines

Long long ago, in a more innocent time, Greg wrote the clarification for
how the DCO should work and that you couldn't make anonymous
contributions, because the sign-off needed to be something we could
check back with.

It was 2006, and nobody reacted to the wording, the whole Facebook 'real
name' controversy was a decade in the future, and nobody even thought
about it.  And despite the language, we've always accepted nicknames and
that language was never meant to be any kind of exclusionary wording.

In fact, even when it became a discussion in other adjacent projects,
apparently nobody even thought to just clarify the language in the
kernel docs, and instead we had projects like the CNCF that had long
discussions about it, and wrote their own clarifications [1] of it.

Just simplify the wording to the point where it shouldn't be causing
unnecessary angst and pain, or scare away people who go by preferred
naming.

Both userspace and kernelspace can pass structs with an uninitialized
'stream' field. Since the check_state() function checks for a non-zero
stream field, suddenly these calls will fails with -EINVAL.

So check in the wrapper functions in v4l2-subdev.c (which are used by both
the kernel and userspace API) if V4L2_SUBDEV_FL_STREAMS is set, and if not,
then zero the stream field.

Currently no drivers set V4L2_SUBDEV_FL_STREAMS, so the stream field will
always be set to 0.

This patch might well be reverted in the future when streams support is
fully enabled and we finalized the userspace API support for this feature.

Improve the source package support in case the dpkg-buildpackage is
directly used to build binary packages.

For cross-compiling, you can set CROSS_COMPILE via the environment
variable, but it is better to set it automatically - set it to
${DEB_HOST_GNU_TYPE}- if we are cross-compiling but not from the top
Makefile.

The generated source package may be carried to a different build
environment, which may have a different compiler installed.
Run olddefconfig first to set new CONFIG options to their default
values without prompting.

Take KERNELRELEASE and KBUILD_BUILD_VERSION from the version field of
debian/changelog in case it is updated afterwards.

The clean target needs ARCH=${ARCH} to clean up the tree for the correct
architecture. 'make (bin)deb-pkg' skips cleaning, but the preclean hook
may be executed if dpkg-buildpackage is directly used.

The binary-arch target does not need KERNELRELEASE because it is not
updated during the installation. KBUILD_BUILD_VERSION is not needed
either because binary-arch does not build vmlinux.

Pull clk updates from Stephen Boyd:
 "We have one small patch to the clk core this time around. It fixes a
  corner case with the CLK_OPS_PARENT_ENABLE flag combined with
  clk_core_is_enabled() where it hangs the system. We'll simply assume
  the clk is disabled if the parent is disabled and the flag is set.
  Trying to turn on the parent to check the enable state of the clk runs
  into system hangs at boot. We let this bake in -next for a couple
  weeks to make sure there aren't any more issues because the last
  attempt to fix this ran into hangs and had to be reverted.

  Note: There were some more patches to the core framework around
  sync_state and disabling unused clks, but I asked for that to be
  reverted from the qcom PR because it isn't ready and we're still
  discussing the best solution on the list.

  Outside of the core clk framework, we have the usual collection of clk
  driver updates and support for new SoCs (which seems to never stop).
  The dirstat is dominated by Qualcomm because they added support for
  quite a few SoCs this time around and also migrated quite a few of
  their drivers to clk_parent_data. The other big diff is in the
  Mediatek clk drivers that saw a significant rework this cycle to
  similarly modernize the code, and we'll see that work continue in the
  next cycle as well. Nothing really jumps out as scary here, except
  that the significant churn in parent data descriptions can have typos
  that go unnoticed. More details below.

  Core:
   - Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled()

  New Drivers:
   - Add a new clk-gpr-mux clock type and use it on i.MX6Q to add ENET
     ref clocks
   - Support for Mediatek MT7891 SoC clks
   - Support for many Qualcomm clk controllers:
      - QDU1000/QRU1000 global clock controller
      - SA8775P global clock controller
      - SM8550 TCSR and display clock controller
      - SM6350 clock controller
      - MSM8996 CBF and APCS clock controllers

  Updates:
   - Various cleanups and improvements to Mediatek clk drivers to reduce
     code size and modernize the drivers
   - Support for Versa 5P49V60 clks
   - Disable R-Car H3 ES1.*, as it was only available to an internal
     development group and needed a lot of quirks and workarounds
   - Add PWM, Compare-Match Timer (TIM), USB, SDHI, and eMMC clocks and
     resets on Renesas RZ/V2M
   - Add display clocks on Renesas R-Car V4H
   - Add Camera Receiving Unit (CRU) clocks and resets on Renesas RZ/G2L
   - Free the imx_uart_clocks even if imx_register_uart_clocks returns
     early
   - Get the stdout clocks count from device tree on i.MX
   - Drop the clock count argument from imx_register_uart_clocks()
   - Keep the uart clocks on i.MX93 for when earlycon is used
   - Fix SPDX comment in i.MX6SLL clocks bindings header
   - Drop some unnecessary spaces from i.MX8ULP clocks bindings header
   - Add imx_obtain_fixed_of_clock() for allowing to add a clock that is
     not configured via devicetree
   - Fix the ENET1 gate configuration for i.MX6UL according to the
     reference manual
   - Add ENET refclock mux support for i.MX6UL
   - Add support for USB host/device configuration on Renesas RZ/N1
   - Add PLL2 programming support, and CAN-FD clocks on Renesas R-Car
     V4H
   - Add D1 CAN bus gates and resets for Allwinner
   - Mark D1 CPUX clock as critical on Allwinner
   - Reuse D1 driver for Allwinner R528/T113
   - Cleanup sunxi-ng Kconfig
   - Fix sunxi-ng kernel-doc issues
   - Model Allwinner H3/H5 DRAM clock as fixed clock
   - Use .determine_rate() instead of .round_rate() for the dualdiv,
     mpll, sclk-div and cpu-dyn-div amlogic clock drivers
   - DDR clocks were marked as critical in the proper clock driver for
     each AT91 SoC such that drivers/memory/atmel-sdramc.c to be deleted
     in the next releases as it only does clock enablement
   - Patch to avoid compiling dt-compat.o for all AT91 SoCs as only some
     of them may use it
   - Support synchronous power_off requests in the qcom GDSC driver for
     proper GPU power collapse
   - Drop test clocks from various Qualcomm clk drivers
   - Update parent references to use clk_parent_data/clk_hw in various
     Qualcomm clk drivers
   - Fixes for the Qualcomm MSM8996 CPU clock controller
   - Transition Qualcomm MSM8974 GCC off the externally defined
     sleep_clk
   - Add GDSCs in the global clock controller for Qualcomm QCS404
   - The SDCC core clocks on Qualcomm SM6115 are moved to floor_ops
   - Programming of clk_dis_wait for GPU CX GDSC on Qualcomm SC7180 and
     SDM845 are moved to use the recently introduced properties in the
     GDSC struct
   - Qualcomm's RPMh clock driver gains SM8550 and SA8775P clocks, and
     the IPA clock is added on a variety of platforms
   - De-duplicate identical clks in Qualcomm SMD RPM clk driver
   - Add a few missing clocks across msm8998, msm8992, msm8916, qcs404
     to Qualcomm SDM RPM clk driver
   - Various Qualcomm clk drivers use devm_pm_runtime_enable() to
     simplify"

Pull kvm updates from Paolo Bonzini:
 "ARM:

   - Provide a virtual cache topology to the guest to avoid
     inconsistencies with migration on heterogenous systems. Non secure
     software has no practical need to traverse the caches by set/way in
     the first place

   - Add support for taking stage-2 access faults in parallel. This was
     an accidental omission in the original parallel faults
     implementation, but should provide a marginal improvement to
     machines w/o FEAT_HAFDBS (such as hardware from the fruit company)

   - A preamble to adding support for nested virtualization to KVM,
     including vEL2 register state, rudimentary nested exception
     handling and masking unsupported features for nested guests

   - Fixes to the PSCI relay that avoid an unexpected host SVE trap when
     resuming a CPU when running pKVM

   - VGIC maintenance interrupt support for the AIC

   - Improvements to the arch timer emulation, primarily aimed at
     reducing the trap overhead of running nested

   - Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
     interest of CI systems

   - Avoid VM-wide stop-the-world operations when a vCPU accesses its
     own redistributor

   - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected
     exceptions in the host

   - Aesthetic and comment/kerneldoc fixes

   - Drop the vestiges of the old Columbia mailing list and add [Oliver]
     as co-maintainer

  RISC-V:

   - Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE

   - Correctly place the guest in S-mode after redirecting a trap to the
     guest

   - Redirect illegal instruction traps to guest

   - SBI PMU support for guest

  s390:

   - Sort out confusion between virtual and physical addresses, which
     currently are the same on s390

   - A new ioctl that performs cmpxchg on guest memory

   - A few fixes

  x86:

   - Change tdp_mmu to a read-only parameter

   - Separate TDP and shadow MMU page fault paths

   - Enable Hyper-V invariant TSC control

   - Fix a variety of APICv and AVIC bugs, some of them real-world, some
     of them affecting architecurally legal but unlikely to happen in
     practice

   - Mark APIC timer as expired if its in one-shot mode and the count
     underflows while the vCPU task was being migrated

   - Advertise support for Intel's new fast REP string features

   - Fix a double-shootdown issue in the emergency reboot code

   - Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give
     SVM similar treatment to VMX

   - Update Xen's TSC info CPUID sub-leaves as appropriate

   - Add support for Hyper-V's extended hypercalls, where "support" at
     this point is just forwarding the hypercalls to userspace

   - Clean up the kvm->lock vs. kvm->srcu sequences when updating the
     PMU and MSR filters

   - One-off fixes and cleanups

   - Fix and cleanup the range-based TLB flushing code, used when KVM is
     running on Hyper-V

   - Add support for filtering PMU events using a mask. If userspace
     wants to restrict heavily what events the guest can use, it can now
     do so without needing an absurd number of filter entries

   - Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
     support is disabled

   - Add PEBS support for Intel Sapphire Rapids

   - Fix a mostly benign overflow bug in SEV's
     send|receive_update_data()

   - Move several SVM-specific flags into vcpu_svm

  x86 Intel:

   - Handle NMI VM-Exits before leaving the noinstr region

   - A few trivial cleanups in the VM-Enter flows

   - Stop enabling VMFUNC for L1 purely to document that KVM doesn't
     support EPTP switching (or any other VM function) for L1

   - Fix a crash when using eVMCS's enlighted MSR bitmaps

  Generic:

   - Clean up the hardware enable and initialization flow, which was
     scattered around multiple arch-specific hooks. Instead, just let
     the arch code call into generic code. Both x86 and ARM should
     benefit from not having to fight common KVM code's notion of how to
     do initialization

   - Account allocations in generic kvm_arch_alloc_vm()

   - Fix a memory leak if coalesced MMIO unregistration fails

  selftests:

   - On x86, cache the CPU vendor (AMD vs. Intel) and use the info to
     emit the correct hypercall instruction instead of relying on KVM to
     patch in VMMCALL

   - Use TAP interface for kvm_binary_stats_test and tsc_msrs_test"

Pull Compute Express Link (CXL) updates from Dan Williams:
 "To date Linux has been dependent on platform-firmware to map CXL RAM
  regions and handle events / errors from devices. With this update we
  can now parse / update the CXL memory layout, and report events /
  errors from devices. This is a precursor for the CXL subsystem to
  handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
  for DDR-attached-DRAM is handled by the EDAC driver where it maps
  system physical address events to a field-replaceable-unit (FRU /
  endpoint device). In general, CXL has the potential to standardize
  what has historically been a pile of memory-controller-specific error
  handling logic.

  Another change of note is the default policy for handling RAM-backed
  device-dax instances. Previously the default access mode was "device",
  mmap(2) a device special file to access memory. The new default is
  "kmem" where the address range is assigned to the core-mm via
  add_memory_driver_managed(). This saves typical users from wondering
  why their platform memory is not visible via free(1) and stuck behind
  a device-file. At the same time it allows expert users to deploy
  policy to, for example, get dedicated access to high performance
  memory, or hide low performance memory from general purpose kernel
  allocations. This affects not only CXL, but also systems with
  high-bandwidth-memory that platform-firmware tags with the
  EFI_MEMORY_SP (special purpose) designation.

  Summary:

   - CXL RAM region enumeration: instantiate 'struct cxl_region' objects
     for platform firmware created memory regions

   - CXL RAM region provisioning: complement the existing PMEM region
     creation support with RAM region support

   - "Soft Reservation" policy change: Online (memory hot-add)
     soft-reserved memory (EFI_MEMORY_SP) by default, but still allow
     for setting aside such memory for dedicated access via device-dax.

   - CXL Events and Interrupts: Takeover CXL event handling from
     platform-firmware (ACPI calls this CXL Memory Error Reporting) and
     export CXL Events via Linux Trace Events.

   - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL
     subsystem interrogate the result of CXL _OSC negotiation.

   - Emulate CXL DVSEC Range Registers as "decoders": Allow for
     first-generation devices that pre-date the definition of the CXL
     HDM Decoder Capability to translate the CXL DVSEC Range Registers
     into 'struct cxl_decoder' objects.

   - Set timestamp: Per spec, set the device timestamp in case of
     hotplug, or if platform-firwmare failed to set it.

   - General fixups: linux-next build issues, non-urgent fixes for
     pre-production hardware, unit test fixes, spelling and debug
     message improvements"

	On each context switch we save the FPU registers on stack
of old process and restore FPU registers from the stack of new one.
That allows us to avoid doing that each time we enter/leave the
kernel mode; however, that can get suboptimal in some cases.

	For one thing, we don't need to bother saving anything
for kernel threads.  For another, if between entering and leaving
the kernel a thread gives CPU up more than once, it will do
useless work, saving the same values every time, only to discard
the saved copy as soon as it returns from switch_to().

	Alternative solution:

* move the array we save into from switch_stack to thread_info
* have a (thread-synchronous) flag set when we save them
* have another flag set when they should be restored on return to userland.
* do *NOT* save/restore them in do_switch_stack()/undo_switch_stack().
* restore on the exit to user mode if the restore flag had
been set.  Clear both flags.
* on context switch, entry to fork/clone/vfork, before entry into do_signal()
and on entry into straced syscall save the registers and set the 'saved' flag
unless it had been already set.
* on context switch set the 'restore' flag as well.
* have copy_thread() set both flags for child, so the registers would be
restored once the child returns to userland.
* use the saved data in setup_sigcontext(); have restore_sigcontext() set both flags
and copy from sigframe to save area.
* teach ptrace to look for FPU registers in thread_info instead of
switch_stack.
* teach isolated accesses to FPU registers (rdfpcr, wrfpcr, etc.)
to check the 'saved' flag (under preempt_disable()) and work with the save area
if it's been set; if 'saved' flag is found upon write access, set 'restore' flag
as well.
