Subject: [RFC PATCH] zcache2 cleanups (s/int/bool + debugfs movement).

Looking at the zcache2 code there were a couple of things that I thought
would make sense to move out of the code. For one thing it makes it easier
to read, and for anoter - it can be cleanly compiled out. It also allows
to have a clean seperation of counters that we _need_ vs the optional ones.
Which means that in the future we could get rid of the optional ones.

This patchset is based on the patchset that Dan sent out
(https://lkml.org/lkml/2012/10/31/790). I've stuck
them (and addressed some review comments) and put them in my branch:

 git://git.kernel.org/pub/scm/linux/kernel/git/konrad/mm.git devel/zcache.v3

I am going to repost the module loading some time later this week - Bob Liu had
some comments that I want to address.

So back to this patchset - it fixes some outstanding compile warnings, cleans
up some of the code, and rips out the debug counters out of zcache-main.c
and sticks them in a debug.c file.

I was hoping it would end up with less code, but sadly it ended up with
a bit more due to the empty non-debug functions.
