Subject: [mm PATCH 0/3] Page fragment updates

This patch series takes care of a few cleanups for the page fragments API.

First we do some renames so that things are much more consistent.  First we
move the page_frag_ portion of the name to the front of the functions
names.  Secondly we split out the cache specific functions from the other
page fragment functions by adding the word "cache" to the name.

Second I did some minor clean-up on the function calls so that they are
more inline with the existing __free_pages calls in terms of how they
operate.

Finally I added a bit of documentation that will hopefully help to explain
some of this.  I plan to revisit this later as we get things more ironed
out in the near future with the changes planned for the DMA setup to
support eXpress Data Path.
