David S. Miller c68e5d39a5 sparc32: Implement hard_smp_processor_id() via instruction patching.
This is the last non-trivial user of btfixup.

Like sparc64, use a special patch section to resolve the various
implementations of how to read the current CPU's ID when we don't
have current_thread_info()->cpu necessarily available.
