KVM/riscv changes for 6.4

- ONE_REG interface to enable/disable SBI extensions
- Zbb extension for Guest/VM
- AIA CSR virtualization

Pull parisc updates from Helge Deller:
 "Two important fixes in here:

   - The argument pointer register was wrong when calling 64-bit
     firmware functions, which may cause random memory corruption or
     crashes.

   - Ensure page alignment in cache flush functions, otherwise not all
     memory might get flushed.

  The rest are cleanups (mmap implementation, panic path) and usual
  smaller updates.

  Summary:

   - Calculate correct argument pointer in real64_call_asm()

   - Cleanup mmap implementation regarding color alignment (John David
     Anglin)

   - Spinlock fixes in panic path (Guilherme G. Piccoli)

   - build doc update for parisc64 (Randy Dunlap)

   - Ensure page alignment in flush functions"

Pull more sysctl updates from Luis Chamberlain:
 "As mentioned on my first pull request for sysctl-next, for v6.4-rc1
  we're very close to being able to deprecating register_sysctl_paths().
  I was going to assess the situation after the first week of the merge
  window.

  That time is now and things are looking good. We only have one which
  had already an ACK for so I'm picking this up here now and the last

Fix the argument pointer (ap) to point to real-mode memory
instead of virtual memory.

It's interesting that this issue hasn't shown up earlier, as this could
have happened with any 64-bit PDC ROM code.

I just noticed it because I suddenly faced a HPMC while trying to execute
the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
text console.

This change simplifies the randomization of file mapping regions. It
reworks the code to remove duplication. The flow is now similar to
that for mips. Finally, we consistently use the do_color_align variable
to determine when color alignment is needed.

Tested on rp3440.

Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined
(which is the case for PA-RISC), __kunmap_local() calls
kunmap_flush_on_unmap(), which may call the parisc flush functions with
a non-page-aligned address and thus the page might not be fully flushed.

This patch ensures that flush_kernel_dcache_page_asm() and
flush_kernel_dcache_page_asm() will always operate on page-aligned
addresses.

The panic notifiers' callbacks execute in an atomic context, with
interrupts/preemption disabled, and all CPUs not running the panic
function are off, so it's very dangerous to wait on a regular
spinlock, there's a risk of deadlock.

Refactor the panic notifier of parisc/power driver to make use
of spin_trylock - for that, we've added a second version of the
soft-power function. Also, some comments were reorganized and
trailing white spaces, useless header inclusion and blank lines
were removed.

The deprecation for register_sysctl_paths() is over. We can rejoice as
we nuke register_sysctl_paths(). The routine register_sysctl_table()
was the only user left of register_sysctl_paths(), so we can now just
open code and move the implementation over to what used to be
to __register_sysctl_paths().

The old dynamic struct ctl_table_set *set is now the point to
sysctl_table_root.default_set.

The old dynamic const struct ctl_path *path was being used in the
routine register_sysctl_paths() with a static:

static const struct ctl_path null_path[] = { {} };

Since this is a null path we can now just simplfy the old routine
and remove its use as its always empty.

This saves us a total of 230 bytes.

register_sysctl_paths() is only required if your child (directories)
have entries and pid_namespace does not. So use register_sysctl_init()
instead where we don't care about the return value and use
register_sysctl() where we do.

Pull pin control updates from Linus Walleij:
 "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and
  the new NXP S32 and nVidia BlueField-3.

  Core changes:

   - Make a lot of pin controllers with GPIO and irqchips immutable,
     i.e. not living structs, but const structs. This is driving a
     changed initiated by the irqchip maintainers.

  New drivers:

   - New driver for the NXP S32 SoC pin controller

   - As part of a thorough cleanup and restructuring of the
     Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were
     folded into the Mediatek directory and the family is renamed
     "mtmips". The Ralink chips live on as Mediatek MIPS family where
     new variants can be added. As part of this work also the device
     tree bindings were reworked.

   - New subdriver for the Qualcomm SM7150 SoC.

   - New subdriver for the Qualcomm IPQ9574 SoC.

   - New driver for the nVidia BlueField-3 SoC.

   - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.

   - Support for the Qualcomm PMI632 mixed signal circuit GPIO.

  Improvements:

   - Add some missing pins and generic cleanups on the Renesas r8a779g0
     and r8a779g0 pin controllers. Generic Renesas extension for power

 "Three fixes to AFS directory handling:

   - Make sure that afs_read_dir() sees any increase in file size if the
     file unexpectedly changed on the server (e.g. due to another client
     making a change).

   - Make afs_getattr() always return the server's dir file size, not
     the locally edited one, so that pagecache eviction doesn't cause
     the dir file size to change unexpectedly.

   - Prevent afs_read_dir() from getting into an endless loop if the

afs_read_dir fetches an amount of data that's based on what the inode
size is thought to be.  If the file on the server is larger than what
was fetched, the code rechecks i_size and retries.  If the local i_size
was not properly updated, this can lead to an endless loop of fetching
i_size from the server and noticing each time that the size is larger on
the server.

If it is known that the remote size is larger than i_size, bump up the
fetch size to that size.

Fix afs_getattr() to report the server's idea of the file size of a
directory rather than the local size.  The local size may differ as we edit
the local copy to avoid having to redownload it and we may end up with a
differently structured blob of a different size.

However, if the directory is discarded from the pagecache we then download
it again and the user may see the directory file size apparently change.

If the data version returned from the server is larger than expected,
the local data is invalidated, but we may still want to note the remote
file size.

Since we're setting change_size, we have to also set data_changed
for the i_size to get updated.

Pull kvm updates from Paolo Bonzini:
 "s390:

   - More phys_to_virt conversions

   - Improvement of AP management for VSIE (nested virtualization)

  ARM64:

   - Numerous fixes for the pathological lock inversion issue that
     plagued KVM/arm64 since... forever.

   - New framework allowing SMCCC-compliant hypercalls to be forwarded
     to userspace, hopefully paving the way for some more features being
     moved to VMMs rather than be implemented in the kernel.

   - Large rework of the timer code to allow a VM-wide offset to be
     applied to both virtual and physical counters as well as a
     per-timer, per-vcpu offset that complements the global one. This
     last part allows the NV timer code to be implemented on top.

   - A small set of fixes to make sure that we don't change anything
     affecting the EL1&0 translation regime just after having having
     taken an exception to EL2 until we have executed a DSB. This
     ensures that speculative walks started in EL1&0 have completed.

   - The usual selftest fixes and improvements.

  x86:

   - Optimize CR0.WP toggling by avoiding an MMU reload when TDP is
     enabled, and by giving the guest control of CR0.WP when EPT is
     enabled on VMX (VMX-only because SVM doesn't support per-bit
     controls)

   - Add CR0/CR4 helpers to query single bits, and clean up related code
     where KVM was interpreting kvm_read_cr4_bits()'s "unsigned long"
     return as a bool

   - Move AMD_PSFD to cpufeatures.h and purge KVM's definition

   - Avoid unnecessary writes+flushes when the guest is only adding new
     PTEs

   - Overhaul .sync_page() and .invlpg() to utilize .sync_page()'s
     optimizations when emulating invalidations

   - Clean up the range-based flushing APIs

   - Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a
     single A/D bit using a LOCK AND instead of XCHG, and skip all of
     the "handle changed SPTE" overhead associated with writing the
     entire entry

   - Track the number of "tail" entries in a pte_list_desc to avoid
     having to walk (potentially) all descriptors during insertion and
     deletion, which gets quite expensive if the guest is spamming
     fork()

   - Disallow virtualizing legacy LBRs if architectural LBRs are
     available, the two are mutually exclusive in hardware

   - Disallow writes to immutable feature MSRs (notably
     PERF_CAPABILITIES) after KVM_RUN, similar to CPUID features

   - Overhaul the vmx_pmu_caps selftest to better validate
     PERF_CAPABILITIES

   - Apply PMU filters to emulated events and add test coverage to the
     pmu_event_filter selftest

   - AMD SVM:
       - Add support for virtual NMIs
       - Fixes for edge cases related to virtual interrupts

   - Intel AMX:
       - Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if
         XTILE_DATA is not being reported due to userspace not opting in
         via prctl()
       - Fix a bug in emulation of ENCLS in compatibility mode
       - Allow emulation of NOP and PAUSE for L2
       - AMX selftests improvements
       - Misc cleanups

  MIPS:

   - Constify MIPS's internal callbacks (a leftover from the hardware
     enabling rework that landed in 6.3)

  Generic:

   - Drop unnecessary casts from "void *" throughout kvm_main.c

   - Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the
     struct size by 8 bytes on 64-bit kernels by utilizing a padding
     hole
