Subject: [PATCH 10/15] tools headers kvm: Sync linux/kvm.h with the kernel sources

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To pick up the changes from:

  9a5788c615f5 ("KVM: PPC: Book3S HV: Add a capability for enabling secure guests")
  3c9bd4006bfc ("KVM: x86: enable dirty log gradually in small chunks")
  13da9ae1cdbf ("KVM: s390: protvirt: introduce and enable KVM_CAP_S390_PROTECTED")
  e0d2773d487c ("KVM: s390: protvirt: UV calls in support of diag308 0, 1")
  19e122776886 ("KVM: S390: protvirt: Introduce instruction data area bounce buffer")
  29b40f105ec8 ("KVM: s390: protvirt: Add initial vm and cpu lifecycle handling")

So far we're ignoring those arch specific ioctls, we need to revisit
this at some time to have arch specific tables, etc:

  $ grep S390 tools/perf/trace/beauty/kvm_ioctl.sh
      egrep -v " ((ARM|PPC|S390)_|[GS]ET_(DEBUGREGS|PIT2|XSAVE|TSC_KHZ)|CREATE_SPAPR_TCE_64)" | \
  $

This addresses these tools/perf build warnings:

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