5134596cae perf/x86/msr: Add missing Intel models 
This patch presumes that Kabylake and Skylake Server will be the
same as the existing Skylake parts and adds them to the MSR
events code.

Also add handling for "WESTMERE2".

353bf605a7 perf/x86/msr: Use Intel family macros for MSR events code 
Use the new INTEL_MODEL_* macros for arch/x86/events/msr.c.

This code appears to be missing handling for "WESTMERE2" and
"SKYLAKE_X".

3c3116b745 perf/x86/msr: Fix SMI overflow 
We compute 'delta' and properly sign extend it and then ignore it and
recompute the raw value, loosing the sign extention.

aaf248848d perf/x86/msr: Add AMD IRPERF (Instructions Retired) performance counter 
AMD Zeppelin (Family 17h, Model 00h) introduces an instructions
retired performance counter which is indicated by
CPUID.8000_0008H:EBX[1]. A dedicated Instructions Retired MSR register
(MSR 0xC000_000E9) increments once for every instruction retired.

8a22426184 perf/x86/msr: Add AMD PTSC (Performance Time-Stamp Counter) support 
AMD Carrizo (Family 15h, Model 60h) introduces a time-stamp counter
which is indicated by CPUID.8000_0001H:ECX[27]. It increments at a 100
MHz rate in all P-states, and C states, S0, or S1. The frequency is
about 100MHz. This counter will be used to calculate processor power
and other parts. So add an interface into the MSR PMU to get the PTSC
counter value.
