[PATCH] cleanup bio_map_user and helper
Bart did this patch, I changed it a bit. Basically it cleans the mapping
interface up a bit, and adds a little helper to set up the request from
the bio.
In addition, it fixes a long standing bug where bio_map_user() would
call blk_queue_bounce() without the direction bit being set, auch.
- Abstract out bio request preparation
- Have bio_map_user() set data direction (fixes bug where blk_queue_bounce()
is called without it set)
- Split bio_map_user() in two
