Subject: [PATCH 2/7] tools include: Sync kernel ABI headers with tooling headers
From: Ingo Molnar <mingo@...nel.org>
Time for a sync with ABI/uapi headers with the upcoming v4.14 kernel.
None of the ABI changes require any source code level changes to our
existing in-kernel tooling code:
- tools/arch/s390/include/uapi/asm/kvm.h:
New KVM_S390_VM_TOD_EXT ABI, not used by in-kernel tooling.
- tools/arch/x86/include/asm/cpufeatures.h:
tools/arch/x86/include/asm/disabled-features.h:
New PCID, SME and VGIF x86 CPU feature bits defined.
- tools/include/asm-generic/hugetlb_encode.h:
tools/include/uapi/asm-generic/mman-common.h:
tools/include/uapi/linux/mman.h:
Two new madvise() flags, plus a hugetlb system call mmap flags
restructuring/extension changes.
- tools/include/uapi/drm/drm.h:
tools/include/uapi/drm/i915_drm.h:
New drm_syncobj_create flags definitions, new drm_syncobj_wait
and drm_syncobj_array ABIs. DRM_I915_PERF_* calls and a new
I915_PARAM_HAS_EXEC_FENCE_ARRAY ABI for the Intel driver.
- tools/include/uapi/linux/bpf.h:
New bpf_sock fields (::mark and ::priority), new XDP_REDIRECT
action, new kvm_ppc_smmu_info fields (::data_keys, instr_keys)
