Right, so looking at the code, early_identify_cpu()/identify_boot_cpu()
could call a
mca_bsp_init()
or so which does the once, vendor-agnostic setup.
identify_cpu->mcheck_cpu_init()
already does both the BSP and AP per-CPU init.
With such a split, I think we'll have all the proper places to do setup
at the right time without hackery.

Yes.

I think you mean parallel hotplug but that's for the APs only.
Thx.
