Subject: linux-next: manual merge of the block tree with Linus' tree

Hi Jens,

Today's linux-next merge of the block tree got a conflict in
block/blk-core.c between commit 5e00d1b5b4c10fb839afd5ce61db8e24339454b0
("BLOCK: fix bio.bi_rw handling") from Linus' tree (v2.6.36-rc4) and
commit 28e7d1845216538303bb95d679d8fd4de50e2f1a ("block: drop barrier
ordering by queue draining") from the block tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
