Is that meant to be a 64 _byte_ alignment? By default, it is
already aligned to 64 bit.
If 64 byte is some magic requirement by the hypervisor, you
might want to make that explicit by using a constant definition
for it.

CPU_FTRS_CELL already contains CPU_FTR_SMT, why do you need to enable
it explicitly?
