* 'for-2.6.31' of git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6: (28 commits) ide-tape: fix debug call alim15x3: Remove historical hacks, re-enable init_hwif for PowerPC ide-dma: don't reset request fields on dma_timeout_retry() ide: drop rq->data handling from ide_map_sg() ide-atapi: kill unused fields and callbacks ide-tape: simplify read/write functions ide-tape: use byte size instead of sectors on rw issue functions ide-tape: unify r/w init paths ide-tape: kill idetape_bh ide-tape: use standard data transfer mechanism ide-tape: use single continuous buffer ide-atapi,tape,floppy: allow ->pc_callback() to change rq->data_len ide-tape,floppy: fix failed command completion after request sense ide-pm: don't abuse rq->data ide-cd,atapi: use bio for internal commands ide-atapi: convert ide-{floppy,tape} to using preallocated sense buffer ide-cd: convert to using generic sense request ide: add helpers for preparing sense requests ide-cd: don't abuse rq->buffer ide-atapi: don't abuse rq->buffer ...
