[PATCH urgent 0/2] x86: vm86 fix and test

[Andy Lutomirski]

Calling vm86 and then forking will corrupt things.  Fix it.

This is for x86/urgent.  It fixes a 4.3 regression.

Andy Lutomirski (2):
  selftests/x86: Add a fork() to entry_from_vm86 to catch fork bugs
  x86/vm86: Set thread.vm86 to NULL on fork/clone
