Laura Abbott b51ef52df7 x86/cpu: Restore MSR_IA32_ENERGY_PERF_BIAS after resume ... MSR_IA32_ENERGY_PERF_BIAS is lost after suspend/resume: x86_energy_perf_policy -r before cpu0: 0x0000000000000006 cpu1: 0x0000000000000006 cpu2: 0x0000000000000006 cpu3: 0x0000000000000006 cpu4: 0x0000000000000006 cpu5: 0x0000000000000006 cpu6: 0x0000000000000006 cpu7: 0x0000000000000006 after cpu0: 0x0000000000000000 cpu1: 0x0000000000000006 cpu2: 0x0000000000000006 cpu3: 0x0000000000000006 cpu4: 0x0000000000000006 cpu5: 0x0000000000000006 cpu6: 0x0000000000000006 cpu7: 0x0000000000000006 Resulting in inconsistent energy policy settings across CPUs. This register is set via init_intel() at bootup. During resume, the secondary CPUs are brought online again and init_intel() is callled which re-initializes the register. The boot CPU however never reinitializes the register. Add a syscore callback to reinitialize the register for the boot CPU.
