Changki Kim 56da24e7a9 ANDROID: vendor_hooks: Add new android vendor hooks for ipi stop
When a kernel panic occurred, it is sometimes caused by a other cpu
than the panic cpu. When a panic cpu sends smp stop IPI, it can help to
solve the problem even more if aonther cpu stores registers and
run cache flush.
