Hi Ross,

Say, most of the places (file names, function and variable names, and even
print statements) where this patchset uses hmem or HMEM, it really seems to
mean, the Heterogeneous Memory Attribute Table. That's not *always* true, but
given that it's a pretty severe naming conflict, how about just changing:

hmem --> hmat
HMEM --> HMAT

...everywhere? Then you still have Heterogeneous Memory in the name, but
there is enough lexical distance (is that a thing? haha) between HMM and HMAT
to keep us all sane. :)

With or without the above suggestion, there are a few places (Kconfig, comments,
prints) where we can more easily make it clear that HMM != HMEM (or HMAT), 
so for those I can just comment on them separately in the individual patches.

thanks,
john h
