Michael Ellerman 719d1cd867 [PATCH] ppc64: Replace custom locking code with a spinlock ... The hvlpevent_queue (formally ItLpQueue) has a member called xInUseWord which is used for serialising access to the queue. Because it's a word (ie. 32 bit) there's a custom 32-bit version of test_and_set_bit() or thereabouts in ItLpQueue.c. The xInUseWord is not shared with they hypervisor, so we can replace it with a spinlock and remove the custom code. There is also another locking mechanism (ItLpQueueInProcess). This is redundant because it's only manipulated while the lock's held. Remove it.
