This patch showed up in linux-next tag next-20130605 and appears to be the
cause of a boot failure on my ia64 HP rx2600 system. It panics with
the message:

Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or
DIG kernel

Reverting this from next-20130605 fixes my problem and I can boot again.

So please don't pull.
