Subject: [PATCH 2/2] powerpc/watchdog: include linux/processor.h for
 spin_until_cond

From: Sudeep Holla <sudeep.holla@....com>

This implementation uses spin_until_cond in wd_smp_lock including
neither linux/processor.h nor asm/processor.h

This patch includes linux/processor.h here for spin_until_cond usage.
