Merge branch 'signal-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull signal cleanup from Eric Biederman:
 "Remove a never used HP-UX compatibility from parisc headers and
  consolidating the SA_* flags definitions into a generic header as much
  as possible.

  We only have 32 SA_* flag bits total, so we need to be careful. But as
  this is the first addition in a decade or so I think we are fine for
  the forseeable future"
