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) Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Milian Wolff <milian.wolff@kdab.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Taeung Song <treeze.taeung@gmail.com> Cc: Wang Nan <wangnan0@huawei.com> Cc: Yao Jin <yao.jin@linux.intel.com> Link: http://lkml.kernel.org/r/20170913073823.lxmi4c7ejqlfabjx@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
