Subject: [PATCH 0/3] Stuff for 4.2 (including a revert)

Hi all-

Patch 1 is a revert, Cc'd to stable.  I haven't tried to write a
real test for the bug, but the code definitely looks buggy.  I
intent to fix it for real as part of converting more of the syscall
entry code to C, but this is a better fix for now.

Patch 2 fixes selftests fallout from the sigcontext revert.

Patch 3 is a new test that I thought I added but apparently didn't.
It's probably 4.3 material, but it's related to patch 1, so I'm
sending them together.

Andy Lutomirski (3):
  Revert "sched/x86_64: Don't save flags on context switch"
  selftests/x86: Disable sigreturn_64
  selftests/x86: Add syscall_nt selftest
