No problem, happy to assist. I think this did the trick! preliminary
testing shows
that this now works on alpha! I guess the offset information in paddr was lost
by doing "paddr &= PAGE_MASK" before retrieving the offset, well spotted!
I'll keep running the system with some load to make sure there is nothing else
we haven't spotted yet, but so far so good. I'll keep you posted.
Will you be putting out a v2 of this patchset with these updates?

Magnus Lindholm
