Merge tag 'x86_mm_for_7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm updates from Dave Hansen:
"There are two things in here of note. First, there are fixes to reduce
the time that the TLB flushing code sits around with interrupts
disabled. It should be well tested, but it's certainly something to
keep an eye on.
Second is a little back-and-forth in the interactions between the
set_memory*() locking and DEBUG_PAGEALLOC. There was a slightly
painful re-discovery of why DEBUG_PAGEALLOC has special locking rules,
but the code did end up better for it.
Summary:
- Fix pkey_alloc() return value when pkeys are not supported
- Allow preemption during IPI completion waiting to improve wakeup
latency
- Convert more x86 page table code to ptdescs
- Fixes and cleanups for set_memory*() locking, mostly around large
pages"
