Subject: [PATCH urgent 0/2] x86: vm86 fix and test
Date: Fri, 30 Oct 2015 22:42:44 -0700	[thread overview]
Message-ID: <cover.1446270067.git.luto@kernel.org> (raw)

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
