Subject: [PATCH v2 0/2] x86/entry: 32-bit facepalm fixes

Fixes a (correct) warning and an oops.  Oddly, both seem to only
cause problems on some configurations.  The second one presumably
only survived my testing because I didn't test a threaded program.

The first patch is a bit ugly.  If that's a problem, suggestions
are welcome.

Changes from v1: No longer breaks 64-bit builds.

Andy Lutomirski (2):
  x86/entry/32: Fix entry_INT80_32 to expect interrupts to be on
  x86/entry/32: Fix FS and GS restore in opportunistic SYSEXIT
