Once it goes via stable, I throw it at the stable pile to ease their
rebase on top stable.

I dropped from your queue:

| ARM: move vmalloc() lazy-page table population
| ARM: move is_permission_fault() and is_translation_fault() to fault.h
| ARM: use BIT() and GENMASK() for fault status register fields
| ARM: move FSR fault status definitions before fsr_fs()
| ARM: provide individual is_translation_fault() and is_permission_fault()

as far as I can tell, it is just shuffling code around. Not strictly
needed for the backport. The "grouping" patch that I sent stable@ is
also moving code around but the following "fix" needs the forward
declaration so it goes in as a requirement.
I don't see the need for these.
