percpu error in linux-next (CONFIG_SMP=n)

hi Tejun,

drivers/base/cpu.c: line 100: fails to build when CONFIG_SMP=n:

addr = per_cpu_ptr_to_phys(per_cpu_ptr(crash_notes, cpunum));

Can you suggest a fix for that, please?

thanks,

Commit 3b034b0d084221596bf35c8d893e1d4d5477b9cc implemented
per_cpu_ptr_to_phys() but forgot to add UP definition. Add UP
definition which is simple wrapper around __pa().

Oops, right, UP definition was missing. This patch should do it.

Thanks.
