9e7f4d451e [PATCH] lockdep: rename DEBUG_WARN_ON() 
Rename DEBUG_WARN_ON() to the less generic DEBUG_LOCKS_WARN_ON() name, so that
it's clear that this is a lock-debugging internal mechanism.

1fb00c6cbd [PATCH] work around ppc64 bootup bug by making mutex-debugging save/restore irqs 
It seems ppc64 wants to lock mutexes in early bootup code, with interrupts
disabled, and they expect interrupts to stay disabled, else they crash.

Work around this bug by making mutex debugging variants save/restore irq
flags.
