causes build errors in linux-next of NOV. 17.

see http://lkml.org/lkml/2010/11/17/339
and http://lkml.org/lkml/2010/11/17/365


smp_lock.h was removed from hardirq.h.  smp_lock.h provided the function prototype
for kernel_locked().  Should source files now #include <linux/smp_lock.h> ?
even when not being built for SMP?
