[PATCH 4/7] x86 power: define RAPL MSRs

From: Len Brown
Date: Wed Nov 14 2012 - 15:43:29 EST


From: Len Brown <len.brown@xxxxxxxxx>

The Run Time Average Power Limiting interface
is currently model specific, present on Sandy Bridge
and Ivy Bridge processors.

These #defines correspond to documentation in the latest
"Intel 64 and IA-32 Architectures Software Developer Manual",
plus some typos in that document corrected.
