tools headers UAPI: Sync linux/kvm.h with the kernel sources

2021-11-18T13:08:07+00:00

To pick the changes in:

  b56639318bb2be66 ("KVM: SEV: Add support for SEV intra host migration")
  e615e355894e6197 ("KVM: x86: On emulation failure, convey the exit reason, etc. to userspace")
  a9d496d8e08ca1eb ("KVM: x86: Clarify the kvm_run.emulation_failure structure layout")
  c68dc1b577eabd56 ("KVM: x86: Report host tsc and realtime values in KVM_GET_CLOCK")
  dea8ee31a0392775 ("RISC-V: KVM: Add SBI v0.1 support")

That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.

This is also by now used by tools/testing/selftests/kvm/, a simple test
build succeeded.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

2021-11-10T19:29:30+00:00

Pull arm64 fixes from Will Deacon:

 - Fix double-evaluation of 'pte' macro argument when using 52-bit PAs

 - Fix signedness of some MTE prctl PR_* constants

 - Fix kmemleak memory usage by skipping early pgtable allocations

 - Fix printing of CPU feature register strings

 - Remove redundant -nostdlib linker flag for vDSO binaries

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
  arm64: pgtable: make __pte_to_phys/__phys_to_pte_val inline functions
  arm64: Track no early_pgtable_alloc() for kmemleak
  arm64: mte: change PR_MTE_TCF_NONE back into an unsigned long
  arm64: vdso: remove -nostdlib compiler flag
  arm64: arm64_ftr_reg->name may not be a human-readable string

arm64: mte: change PR_MTE_TCF_NONE back into an unsigned long

2021-11-08T10:04:33+00:00

This constant was previously an unsigned long, but was changed
into an int in commit 433c38f40f6a ("arm64: mte: change ASYNC and
SYNC TCF settings into bitfields"). This ended up causing spurious
unsigned-signed comparison warnings in expressions such as:

(x & PR_MTE_TCF_MASK) != PR_MTE_TCF_NONE

Therefore, change it back into an unsigned long to silence these
warnings.
