Subject: [PATCH v5 01/11] perf/x86/intel/pt: Move Intel-PT MSR bit definitions to a public header
From: Chao Peng <chao.p.peng@...ux.intel.com>
Intel Processor Trace virtualization enabling in guest need
to use these MSR bits, so move them to public header msr-index.h.
Introduce RTIT_CTL_FABRIC_EN and sync the definitions to
latest spec.
