[git pull] IOMMU fixes and updates

[Joerg Roedel]

Hi Linus,

I know that this pull-request comes too late, but these changes had kvm
dependencies (this is the reason I didn't sent these changes via Ingo).
The KVM changes appeared in your tree last friday and as I checked my
prepared branch against the result I found out that the KVM people
rebased the branch I put the largepage changes on. So I had to rebase my
largepage branch too to eliminate the old commits and put a new
pull-branch together.
Sadly the KVM branch was rebased to some stage of your tree in the merge
window which didn't even boot my test machine. So I spent the whole day
yesterday to get the result booting and tested. After finding the reason
for the boot crash I passed this issue to Boris which sent a fix for
this one (see http://lkml.org/lkml/2010/3/8/199). Here is the
tested result. With Boris fix it boots and has no know regressions.
Please consider to pull these changes. If you decide thats too late to
pull this it has to wait for the next merge window.

Anyway:
