George V. Neville-Neil f4a9c30419 Fix a panic brought about by writing an MSR without a proper mask.
All of the necessary wrmsr calls are now preceded by a rdmsr
and we leave the reserved bits alone.
Document the bits in the relevant registers for future reference.

Tested by:	mdf
MFC after:	1 week
