  MSR Definitions for Intel(R) Xeon(R) Processor Series 5600.

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