[PATCH] Shut up per_cpu_ptr() on UP
Currently per_cpu_ptr() doesn't really do anything with 'cpu' in the UP
case. This is problematic in the cases where this is the only place the
variable is referenced:
CC kernel/workqueue.o
kernel/workqueue.c: In function `current_is_keventd':
kernel/workqueue.c:460: warning: unused variable `cpu'
