tools include: Sync kernel ABI headers with tooling headers 



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)

/*

 * Several system calls take a flag to request "hugetlb" huge pages.

 * Without further specification, these system calls will use the

 * system's default huge page size.  If a system supports multiple

 * huge page sizes, the desired huge page size can be specified in

 * bits [26:31] of the flag arguments.  The value in these 6 bits

 * will encode the log2 of the huge page size.

 *

 * The following definitions are associated with this huge page size

 * encoding in flag arguments.  System call specific header files

 * that use this encoding should include this file.  They can then

 * provide definitions based on these with their own specific prefix.

 * for example:
