Subject: mtrr/state.c unused?

It looks like <arch/x86/kernel/cpu/mtrr/state.c> is not used by
anything in the kernel.

Besides cleanups, the only relevant patch in the git history is:

commit 2ec1df4130c60d1eb49dc0fa0ed15858fede6b05

    i386: move kernel/cpu/mtrr


which adds it. Hmm...

A

git log -i --pickaxe-all -Sset_mtrr_prepare_save

for example, shows that

    x86: remove long dead cyrix mtrr code

has removed the last callers of those helpers and they're now unused.
They should go if we don't need them anymore.
