Merge branch 'core-signals-for-linus' of git://git./linux/kernel/git/tip/tip

Pull core signal updates from Ingo Molnar:
 "These updates from Stas Sergeev and Andy Lutomirski, improve the
  sigaltstack interface by extending its ABI with the SS_AUTODISARM
  feature, which makes it possible to use swapcontext() in a sighandler
  that works on sigaltstack.  Without this flag, the subsequent signal
  will corrupt the state of the switched-away sighandler.

  The inspiration is more robust dosemu signal handling"

* 'core-signals-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  signals/sigaltstack: Change SS_AUTODISARM to (1U << 31)
  signals/sigaltstack: Report current flag bits in sigaltstack()
  selftests/sigaltstack: Fix the sigaltstack test on old kernels
  signals/sigaltstack: If SS_AUTODISARM, bypass on_sig_stack()
  selftests/sigaltstack: Add new testcase for sigaltstack(SS_ONSTACK|SS_AUTODISARM)
  signals/sigaltstack: Implement SS_AUTODISARM flag
  signals/sigaltstack: Prepare to add new SS_xxx flags
  signals/sigaltstack, x86/signals: Unify the x86 sigaltstack check with other architectures
