[GIT PULL] IOMMU fixes for -rc5

[Will Deacon]

Hi Linus,

As mentioned at [1], I'm temporarily helping out with the IOMMU tree so
here are some fixes I've collected for -rc5, including an update to
MAINTAINERS as suggested by Joerg on IRC.

Anyway, two straightforward vt-d fixes summarised in the tag. I ended up
pulling in some x86 fixes from tip which you already merged for -rc4, as
the DMAR build failure was introduced there and so I needed that in order
to apply the fix.

Please pull.

Cheers,

Will
