Problem Description:

acpi-cpufreq driver does a P-state get after a P-state set, in order to verify 
whether set went through successfully. This test is kind of redundant as set 
goes throught most of the times, and the test is also expensive as a get of P-
states can take a lot of time (same as a set operation) as it goes through SMM 
mode. Effectively, we are doubling the P-state latency due to this get 
opertion. 

The attached patch removes that check unless explicitly asked by 
acpi_pstate_strict parameter.
