Well, smashed stack in romstage -error is no longer in the log,
possibly because this boot used MRC cache now.

With config PARALLEL_CPU_INIT=y so SMP / SMM init in initialize_cpus()
will never call wait_other_cpus() at all. That actually regressed in
my commit 0cc2ce4 [1] but I can't test if reverting it solves this for
you. I'll push a regression fix soonish for review.
