lib: atomic64: Change the type of local lock to raw_spinlock_t
There are still some leftovers of commit f59ca058 [locking, lib/atomic64: Annotate atomic64_lock::lock as raw] [ tglx: Seems I picked the wrong version of that patch :( ] Signed-off-by: Yong Zhang <yong.zhang0@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Shan Hai <haishan.bai@gmail.com> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Link: http://lkml.kernel.org/r/20110914074924.GA16096@zhy Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
