Subject: [PATCH] zcache/debug: compiler failure on PPC64.

From: Konrad Rzeszutek Wilk <[email-masked]>
Date: Wed, 6 Mar 2013 19:13:36 -0500

On PPC64 we get this:
In file included from drivers/staging/zcache/debug.c:2:
drivers/staging/zcache/debug.h: In function 'dec_zcache_obj_count':
drivers/staging/zcache/debug.h:16: error: implicit declaration of function 'BUG_ON'

This simple patch adds the appropiate header file to finish
the compile.
