PATCH 1/1 add a Pentium M config option

Hi Linus,

the patch below is in -mm for some time.

Could you apply it?

TIA
Adrian

Support Pentium M and Pentium-4 M :

- add MPENTIUMM (equivalent to PENTIUMIII except for a bigger X86_L1_CACHE_SHIFT)
- document that MPENTIUM4 is the right choice for a Pentium-4 M
