[PATCH 0/4] SS_AUTODISARM fixes and an ABI change

[Andy Lutomirski]

The first three are fixes IMO.  The fourth changes the SS_AUTODISARM
bit.  I'm assuming that's okay, as the bit has existed in -tip for
less than a day.

Andy Lutomirski (4):
  signals/sigaltstack: If SS_AUTODISARM, bypass on_sig_stack
  selftests/sigaltstack: Fix the sas test on old kernels
  signals/sigaltstack: Report current flag bits in sigaltstack()
  signals/sigaltstack: Change SS_AUTODISARM to (1U << 31)
