x86/process: Clear hardware feedback history for AMD processors
Incorporate a mechanism within the context switching code to reset the
hardware history for AMD processors. Specifically, when a task is switched in,
the class ID is read and the hardware workload classification history of the
CPU firmware is reset. Then, the workload classification for the next running
thread is begun.
