Subject[PATCH v2 0/2] x86/mm/64: vmalloc pgd synchronization cleanups/fixes
Hi all-

Patch 1 is a regression fix and should go to linus and -stable. (Not
necessarily x86/pti. It's needed in 4.14, but if anyone backports
real PTI earlier than 4.14, this patch will *not* be needed. The
regression doesn't really have anything to do with PTI.)

Patch 2 should probably go to normal -tip or even just wait for
Konstantin's ack.

Andy Lutomirski (2):
x86/mm/64: Fix vmapped stack syncing on very-large-memory 4-level
x86/mm/64: Tighten up vmalloc_fault() sanity checks on 5-level kernels
