With your patch,

PatchSmmSaveStateMap patches the SMM entry (code) and SmmSaveState
region (data) for each core, which can be improved to flush TLB once
after all the memory entries have been patched.
FlushTlbForAll flushes TLB for each core in serial, which can be
improved to flush TLB in parrallel.
