Sync (copy) the following v4.12 kernel headers to the tooling headers:
arch/x86/include/asm/disabled-features.h:
arch/x86/include/uapi/asm/kvm.h:
arch/powerpc/include/uapi/asm/kvm.h:
arch/s390/include/uapi/asm/kvm.h:
arch/arm/include/uapi/asm/kvm.h:
arch/arm64/include/uapi/asm/kvm.h:
- 'struct kvm_sync_regs' got changed in an ABI-incompatible way,
fortunately none of the (in-kernel) tooling relied on it
- new KVM_DEV calls added
arch/x86/include/asm/required-features.h:
- 5-level paging hardware ABI detail added
arch/x86/include/asm/cpufeatures.h:
- new CPU feature added
arch/x86/include/uapi/asm/vmx.h:
- new VMX exit conditions
None of the changes requires fixes in the tooling source code.

To pick the changes from:
1b07304c58 ("KVM: nVMX: support descriptor table exits")
That adds entries to VMX_EXIT_REASONS, that is used by
tools/perf/arch/x86/util/kvm-stat.c.
This also picks the changes in:
1dc35dacc1 ("KVM: nVMX: check host CR3 on vmentry and vmexit")
But these are not used in 'perf kvm stat', do it just to silence the
kernel/tools file cache coherency detector:
$ make -C tools/perf
make: Entering directory '/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build

There were changes related to the deprecation of the "pcommit"
instruction:
fd1d961dd6 ("x86/insn: remove pcommit")
dfa169bbee ("Revert "KVM: x86: add pcommit support"")
No need to update anything in the tools, as "pcommit" wasn't being
listed on the VMX_EXIT_REASONS in the tools/perf/arch/x86/util/kvm-stat.c
file.
Just grab fresh copies of these files to silence the file cache
coherency detector:
$ make -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory '/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build
