Subject: [PATCH v2 0/2] x86/mm/64: vmalloc pgd synchronization cleanups/fixes
Date: Thu, 25 Jan 2018 13:12:13 -0800
Message-ID: <cover.1516914529.git.luto@kernel.org> (raw)

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
    systems
  x86/mm/64: Tighten up vmalloc_fault() sanity checks on 5-level kernels
