Will Deacon	60ca1e5a20	mmiowb: Hook up mmiowb helpers to spinlocks and generic I/O accessors ... Removing explicit calls to mmiowb() from driver code means that we must now call into the generic mmiowb_spin_{lock,unlock}() functions from the core spinlock code. In order to elide barriers following critical sections without any I/O writes, we also hook into the asm-generic I/O routines.

Waiman Long	bc88c10d7e	locking/spinlock/debug: Remove spinlock lockup detection code ... The current spinlock lockup detection code can sometimes produce false positives because of the unfairness of the locking algorithm itself. So the lockup detection code is now removed. Instead, we are relying on the NMI watchdog to detect potential lockup. We won't have lockup detection if the watchdog isn't running. The commented-out read-write lock lockup detection code are also removed.
