Peter Zijlstra 21199f27b4 locking/lockdep: Fix hlock->pin_count reset on lock stack rebuilds ... Various people reported hitting the "unpinning an unpinned lock" warning. As it turns out there are 2 places where we take a lock out of the middle of a stack, and in those cases it would fail to preserve the pin_count when rebuilding the lock stack.
