Subject: [PATCH v3 0/3] Add XIP support to ext4

For v3, we've addressed the problem with unwritten extents that Dave
Chinner pointed out.  Rather than testing bh_unwritten() as he suggested,
I opted for checking !buffer_mapped() as block_read_full_page() in
fs/buffer.c does.  While I'm in that function I renamed the buffer_head
from 'tmp' to 'bh' to follow normal usage.

I also folded the "ext4: Add xip hole punching" patch into the main
"Add XIP functionality" patch since otherwise we're introducing broken
functionality in the middle of the series.
