x86/cpu: Clean up various files a bit
No code changes except printk levels (although some of the K6 mtrr code might be clearer if there were a few as would splitting out some of the intel cache code). Signed-off-by: Alan Cox <alan@linux.intel.com> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
