This is mostly Andy's syscall trampoline stack patches, but also some other preparatory cleanups and enhancements.
Sending this separately to make it (slightly) easier to review.
The Git version of the full queue can be found at:
git git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/mm
Thanks,
Ingo
