This patch results in a bunch of WARNING message with each parisc boot if
CONFIG_PROVE_LOCKING and CONFIG_DEBUG_LOCKDEP are enabled.

Is that going to be fixed, or should I disable CONFIG_PROVE_LOCKING
for parisc in my testing ?
They should be looked at and fixed over time. Right now please disable
for now, as I personally won't have time to check as I'm leaving
for vacation. You may send me your .config in private mail though, in
case I find time.
