These are originally from Matthew Wilcox and were part of his huge
"mm,fs,dax: Change ->pmd_fault to ->huge_fault" patch that was part of PUD
support.

I'm breaking these small changes out as they stand on their own and add
useful information to Documentation/filesystems/dax.txt.

So how were you thinking of routing these?  I can take the docs fix, of
course, but part 2 is a bit out of my turf.  If you want to route them
together via another tree that's fine, just let me know.

Thanks,

jon

Interesting, I can't find that cc in my archive anywhere.  It seems it
went astray somewhere?

Thanks,
