Pull more btrfs updates from Chris Mason: "This is part two of my btrfs pull, which is some cleanups and a batch of fixes. Most of the code here is from Jeff Mahoney, making the pointers we pass around internally more consistent and less confusing overall.

bust_spinlocks.c
/*
* lib/bust_spinlocks.c
*
* Provides a minimal bust_spinlocks for architectures which don't have one of their own.
*
* bust_spinlocks() clears any spinlocks which would prevent oops, die(), BUG()
* and panic() information from reaching the user.
