Linus, please pull from
git://git.infradead.org/intel-iommu.git for-linus-20160216
Minor register size and interrupt acknowledgement fixes which only showed
up in testing on newer hardware, but mostly a fix to the MM refcount
handling to prevent a recursive refcount issue when mmap() is used on
the file descriptor associated with a bound PASID.
CQ Tang (1):
iommu/vt-d: Fix 64-bit accesses to 32-bit DMAR_GSTS_REG
David Woodhouse (2):
iommu/vt-d: Fix mm refcounting to hold mm_count not mm_users
iommu/vt-d: Clear PPR bit to ensure we get more page request interrupts
