This involves two changes to the BSP code:

1) register_smp_ops() for BMIPS SMP

2) The CPU1 boot vector on some of the BCM63xx platforms conflicts with
the special interrupt vector (IV).  Move it to 0x8000_0380 at boot time,
to resolve the conflict.

Doesn't scripts/checkpatch.pl complain here? You should not use {} on the single statement branches.
