Subject: [PATCH] mm: rename __alloc_page_frag to page_frag_alloc and
__free_page_frag to page_frag_free
Patch series "Page fragment updates", v4.
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.
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.
This patch (of 3):
This patch renames the page frag functions to be more consistent with
other APIs. Specifically we place the name page_frag first in the name
and then have either an alloc or free call name that we append as the
suffix. This makes it a bit clearer in terms of naming.
In addition we drop the leading double underscores since we are
technically no longer a backing interface and instead the front end that
is called from the networking APIs.

Subject: [PATCH] mm: rename __page_frag functions to __page_frag_cache, drop
order from drain
This patch does two things.
First it goes through and renames the __page_frag prefixed functions to
__page_frag_cache so that we can be clear that we are draining or
refilling the cache, not the frags themselves.
Second we drop the order parameter from __page_frag_cache_drain since we
don't actually need to pass it since all fragments are either order 0 or
must be a compound page.

Subject: [PATCH] MIPS: Add CPU option reporting to /proc/cpuinfo
Many MIPS CPUs have optional CPU features which are not activates for
all CPU cores. Print the CPU options which are implemented in the core
in /proc/cpuinfo. This makes it possible to see what features are
supported and which are not supported. This should cover all standard
MIPS extensions, before it only printed information about the main MIPS
ASEs.
