Very nice series.
Will queue it up for testing to see if anything
obvious breaks.

IIRC, the only place where we used SD_SHARE_CPUPOWER was while assigning
the cpu_power. With the arch_smt_gain() coming into picture, I feel we
can remove the SD_flag.
Not sure what you meant by deprecating the level.
