Some should cause changes in tooling, like the one adding LAST_EXCP, but
the way it is structured end up not making that happen.

The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c,
in the svm_exit_reasons table.

The tools/perf/trace/beauty part has scripts to catch changes and
automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh,
but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch
those automatically.

These were handled by the existing scripts:

  $ tools/perf/trace/beauty/kvm_ioctl.sh &gt; before

Pull kvm updates from Paolo Bonzini:
 "ARM:
   - Move the arch-specific code into arch/arm64/kvm

   - Start the post-32bit cleanup

   - Cherry-pick a few non-invasive pre-NV patches

  x86:
   - Rework of TLB flushing

   - Rework of event injection, especially with respect to nested
     virtualization

   - Nested AMD event injection facelift, building on the rework of
     generic code and fixing a lot of corner cases

   - Nested AMD live migration support

   - Optimization for TSC deadline MSR writes and IPIs

   - Various cleanups

   - Asynchronous page fault cleanups (from tglx, common topic branch
     with tip tree)

   - Interrupt-based delivery of asynchronous "page ready" events (host
     side)

   - Hyper-V MSRs and hypercalls for guest debugging

   - VMX preemption timer fixes

  s390:
   - Cleanups

  Generic:
   - switch vCPU thread wakeup from swait to rcuwait

  The other architectures, and the guest side of the asynchronous page
  fault work, will come next week"

nested VM and its parent VM observe the VMX-preemption timer exit close to
the original expiration deadline.

Revert

  45e29d119e99 ("x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long")

and add a comment to discourage someone else from making the same
mistake again.

It turns out that some user code fails to compile if __X32_SYSCALL_BIT
is unsigned long. See, for example [1] below.

 [ bp: Massage and do the same thing in the respective tools/ header. ]

Picking the changes from:

  5ef8acbdd687 ("KVM: nVMX: Emulate MTF when performing instruction emulation")

Silencing this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/kvm.h' differs from latest version at 'arch/x86/include/uapi/asm/kvm.h'
  diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h

No change in tooling ensues, just the x86 kvm tooling gets rebuilt as
those headers are included in its build:

  $ cp arch/x86/include/uapi/asm/kvm.h tools/arch/x86/include/uapi/asm/kvm.h
  $ make -C tools/perf
  make: Entering directory '/home/acme/git/perf/tools/perf'
    BUILD:   Doing 'make -j12' parallel build

  Auto-detecting system features:
  ...                         dwarf: [ on  ]
  &lt;SNIP&gt;
  ...        disassembler-four-args: [ on  ]

  $

As it doesn't seem to be used there:

  $ grep STATE tools/perf/arch/x86/util/kvm-stat.c
  $

And the 'perf trace' beautifier table generator isn't interested in
these things:

  $ grep regex= tools/perf/trace/beauty/kvm_ioctl.sh
  regex='^#[[:space:]]*define[[:space:]]+KVM_(\w+)[[:space:]]+_IO[RW]*\([[:space:]]*KVMIO[[:space:]]*,[[:space:]]*(0x[[:xdigit:]]+).*'

To pick the changes in:

    0cb8410b90e7 ("kvm: svm: Intercept RDPRU")

That trigger a rebuild in too in tooling:

    CC       /tmp/build/perf/arch/x86/util/kvm-stat.o

But this time around no changes in tooling results, as SVM_EXIT_RDPRU
wasn't added to SVM_EXIT_REASONS, that is used in kvm-stat.c.

And addresses this perf build warnings:
