Nick,
We're working to slowly get the new DRM memory manager into the
mainstream kernel.
This means we have a need for the page fault handler patch you wrote
some time ago.
I guess we could take the no_pfn() route, but that would need a check
for racing
unmap_mapping_range(), and other problems may arise.
What is the current status and plans for inclusion of the fault() code?
Thanks,
Thomas Hellstrom

Hi Thomas,
fault should have gone in already, but the ordering of my patchset was
a little bit unfortunate :P
I will submit them to Andrew later today.
