  MSR Definitions for Pentium Processors.\r
\r
  Provides defines for Machine Specific Registers(MSR) indexes. Data structures\r
  are provided for MSRs that contain one or more bit fields.  If the MSR value\r
  returned is a single 32-bit or 64-bit value, then a data structure is not\r
  provided for that MSR.\r
