Subject: [PATCH] perf/x86/uncore: split Intel uncore driver to smaller files
split Intel uncore driver into four files:
- perf_event_intel_uncore.c: general functions of Intel uncore driver.
- perf_event_intel_uncore_nhmex.c: hardware specific code for
Nehalem-EX/Westmere-EX
- perf_event_intel_uncore_snb.c: hardware specific code for
Nehalem/SandBridge/Haswell
- perf_event_intel_uncore_snbep.c: hardware specific code for
SandyBridge-EP/IvyTown uncore
