Merge git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6: (32 commits) ide-atapi: start dma in a drive-specific way ide-atapi: put the rest of non-ide-cd code into the else-clause of ide_transfer_pc ide-atapi: remove timeout arg to ide_issue_pc ide-cd: remove handler wrappers ide-cd: remove xferlen arg to cdrom_start_packet_command ide-atapi: split drive-specific functionality in ide_issue_pc ide-atapi: assign expiry and timeout based on device type ide-atapi: compute cmd_len based on device type in ide_transfer_pc ide: remove the last ide-scsi remnants ide-atapi: remove ide-scsi remnants from ide_pc_intr() ide-atapi: remove ide-scsi remnants from ide_transfer_pc() ide-atapi: remove ide-scsi remnants from ide_issue_pc ide-cd: move cdrom_timer_expiry to ide-atapi.c ide-atapi: teach ide atapi about drive->waiting_for_dma ide-atapi: accomodate transfer length calculation for ide-cd ide-atapi: setup dma for ide-cd ide-atapi: combine drive-specific assignments ide-atapi: add a dev_is_idecd-inline remove ide-scsi ide-floppy: allocate only toplevel packet commands ...
