Subject[PATCH v13 04/12] perf/x86/intel/pt: Add new bit definitions for PT MSRs
Date
Add bit definitions for Intel PT MSRs to support trace output
directed to the memeory subsystem and holds a count if packet
bytes that have been sent out.

These are required by the upcoming PT support in KVM guests
for MSRs read/write emulation.
