Subject: sh: Hook up hard_smp_processor_id() for INTC2 block.
X-Git-Tag: firefly_0821_release~27981^2~19^2~1
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=027e56e68543780870fda74360ca45e392c50e1c;p=firefly-linux-kernel-4.4.55.git

sh: Hook up hard_smp_processor_id() for INTC2 block.

We need to know the CPU ID in order to calculate the mask and ack
registers effectively. Stub this in for UP.
