Subject: [GIT PULL] IOMMU fixes for -rc4

Hi Linus,

Please pull these three IOMMU fixes for -rc4. The main one is a change
to the Intel IOMMU driver to fix the handling of unaligned addresses
when invalidating the TLB. The fix itself is a bit ugly (the caller does
a bunch of shifting which is then effectively undone later in the
callchain), but Lu has patches to clean all of this up in 5.12.

Thanks,

Will
