tools/include: Sync kernel ABI headers with tooling headers

2017-05-24T07:00:21+00:00

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.

This addresses the following warnings:

  Warning: include/uapi/linux/stat.h differs from kernel
  Warning: arch/x86/include/asm/disabled-features.h differs from kernel
  Warning: arch/x86/include/asm/required-features.h differs from kernel
  Warning: arch/x86/include/asm/cpufeatures.h differs from kernel
  Warning: arch/x86/include/uapi/asm/kvm.h differs from kernel
  Warning: arch/x86/include/uapi/asm/vmx.h differs from kernel
  Warning: arch/powerpc/include/uapi/asm/kvm.h differs from kernel
  Warning: arch/s390/include/uapi/asm/kvm.h differs from kernel
  Warning: arch/arm/include/uapi/asm/kvm.h differs from kernel
  Warning: arch/arm64/include/uapi/asm/kvm.h differs from kernel

Pull KVM updates from Paolo Bonzini:
 "ARM:
   - HYP mode stub supports kexec/kdump on 32-bit
   - improved PMU support
   - virtual interrupt controller performance improvements
   - support for userspace virtual interrupt controller (slower, but
     necessary for KVM on the weird Broadcom SoCs used by the Raspberry
     Pi 3)

  MIPS:
   - basic support for hardware virtualization (ImgTec P5600/P6600/I6400
     and Cavium Octeon III)

  PPC:
   - in-kernel acceleration for VFIO

  s390:
   - support for guests without storage keys
   - adapter interruption suppression

  x86:
   - usual range of nVMX improvements, notably nested EPT support for
     accessed and dirty bits
   - emulation of CPL3 CPUID faulting

  generic:
   - first part of VCPU thread request API
   - kvm_stat improvements"

s390: kvm: Cpu model support for msa6, msa7 and msa8

2017-04-26T12:19:01+00:00

msa6 and msa7 require no changes.
msa8 adds kma instruction and feature area.
