Merge tag 'selinux-pr-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull SELinux updates from Paul Moore:
 "Seven SELinux patches for v4.15, although five of the seven are small
  build fixes and cleanups.

  Of the remaining two patches, the only one worth really calling out is
  Eric's fix for the SELinux filesystem xattr set/remove code; the other
  patch simply converts the SELinux hash table implementation to use
  kmem_cache.

  Eric's setxattr/removexattr tweak converts SELinux back to calling the
  commoncap implementations when the xattr is not SELinux related. The
  immediate win is to fixup filesystem capabilities in user namespaces,
  but it makes things a bit saner overall; more information in the
  commit description"
