Subject: [PATCH v2 0/4] ext4: Add XIP functionality

This patch series addresses the comments received from the first revision.

We didn't change our use of ext4_get_block() to ext4_map_blocks() because it
seems like we would need to add code to deal with journal entries, similar to
what is done in _ext4_get_block().  This seemed more complicated than using a
temporary struct buffer_head on the stack - please let us know if you
disagree.
