acpi-cpufreq: Proper ReadModifyWrite of PERF_CTL MSR
[CPUFREQ] acpi-cpufreq: Proper ReadModifyWrite of PERF_CTL MSR
During recent acpi-cpufreq changes, writing to PERF_CTL msr
changed from RMW of entire 64 bit to RMW of low 32 bit and clearing of
upper 32 bit. Fix it back to do a proper RMW of the MSR.
