[PATCH 0/7] mtrr: cleanups and CONFIG_EMBEDDED usage

From: MichaÅ MirosÅaw
Date: Wed Dec 09 2009 - 02:54:56 EST


A bit of code-cutting in MTRR handling for users of CONFIG_EMBEDDED.
Patches generated on top of current linux-2.6.git (commit 2b876f9...),
tested on 2.6.32 (Pentium4 machine only, all patches at once).
