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/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
