From 6e30437bd42c4d4e9cfc4c40efda00eb83a11cde Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 24 May 2017 08:57:21 +0200 Subject: [PATCH] tools/include: Sync kernel ABI headers with tooling headers 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:
