clean up with bio_kmap_irq() thing properly. remove the micro optimization of _not_ calling kmap_atomic() if this isn't a highmem page. we could keep that and do the inc_preempt_count() ourselves, but I'm not sure it's worth it and this is cleaner.

into hera.kernel.org:/home/axboe/BK/linux-2.5-ide

to bio_kmap/kunmap_irq(), which would screw the preemption count. pass
in rq to ide_unmap_buffer() as well to make the right decision.

o silly IS_PDC4030_DRIVE definition

silly old irq and region registration etc.

o byte -> u8
o use atapi register definitions
o update to ide-iops changes
o driver->end_request() changes
o update to new ide-dma api
o ->reinit to ->attach

o byte -> u8

o ide-iops changes (mainly moving stuff to ide-iops.c)
o byte -> u8
o update to new ide-dma api
o driver->end_request changes
o various style cleanups
o remove ALTSTAT_SCREW_UP stuff
o WAIT_CMD -> WAIT_WORSTCASE interrupt timeout
o add (commented out) various ata commands to match 2.4.20-pre5-ac
o move the flagged_* interrupt handlers

o byte -> u8
o remove various register structs, it's ide general now
o ide-iops changes
o various style cleanups
o update to new ide-dma api
o remove idetape_do_end_request(), dupe of ide core helper
o ->reinit to ->attach changes

o remove low level driver ifdef mess
o allow "host" to register into proc list instead

o byte -> u8
o drive_is_flashcard() moved to probe code
o ide-iops changes
o various cleanups
o remove useless ide_lock debug stuff

o remove *_FUNC abstraction
o remove MODULE ifdefs
o small style changes

o byte -> u8
o small style cleanups

o byte -> u8
o remove various status register definitions, these are now ata (atapi)
  generic
o ide-iops changes
o remove idefloppy_end_request(), dupe of ide core helper
o driver->end_request changes
o lots of style cleanups
o update to new dma interface
o ->reinit to ->attach updates

o ide-iops changes
o driver->end_request and ide_end_request changes
o ->dmaproc() is now split into separate functions
o work on new mmio adapters
o init cleanup

o ide-iops changes
o ide_end_request() now takes a nr_sectors argument, driver->end_request
  as well
o remove idedisk_end_request(), it's a duplicate of ide core helper
o byte -> u8
o ->reinit is now ->attach (to match 2.4.20-pre5-ac)

o kill silly ide_cdrom_end_reuquest() function, it only duplicates
  ide core code.
o use the atapi error, status, ireason, etc types
o use ide-iops functions, not IN_BYTE etc
o use blk_fs_request() where appropriate
o limit retries on MEDIUM_ERROR sense key
o use new ide_end_request() that handles nr_sectors
o rename ->reinit to ->attach
