list_move(A, B) under fs/.

We were using GFP_KERNEL in a handful of places which really wanted
GFP_NOFS. Fix this.

Increase the size of the buffer_head b_size field (only) for 64 bit platforms.
Update some old and moldy comments in and around the structure as well.

The b_size increase allows us to perform larger mappings and allocations for
large I/O requests from userspace, which tie in with other changes allowing
the get_block_t() interface to map multiple blocks at once.

Orphan dir recovery can deadlock with another process in
ocfs2_delete_inode() in some corner cases. Fix this by tracking recovery
state more closely and allowing it to handle inode wipes which might
deadlock.

Disable automatic checkpointing of the journal - this is a relic from older
ocfs2 days. Worth quite a bit of performance on longer running single node
tests.

The mount path had incorrectly asked the locking code to wait for recovery
completion, which deadlocks things because recovery waits for mount to
complete first.

this changes if() BUG(); constructs to BUG_ON() which is
cleaner, contains unlikely() and can better optimized away.

Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated

This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.
