Cover letter [PATCH 0/2] Fix and re-enable vsyscall=emulate
The really nice fix (wiring up access_ok failures to be able to raise signals) won't be ready on time for 3.2, so let's try the simpler fix for now.
Changes from the earlier version:
- Clean up the odd ptr==0 check.
- Flip the default back to vsyscall=emulate
