Browse Source 
linux 4.6 x86/cpu: Add advanced power management bits
Bit 11 of CPUID 8000_0007 edx is processor feedback interface.
Bit 12 of CPUID 8000_0007 edx is accumulated power.

Print proper names in /proc/cpuinfo

[missed enabling this 2016 change during previous major cpuinfo update
as no power related changes were made to the Linux files since then]
