aztcd switched to use of gendisk; missing initcall restored (aztcd_init()
and friends used to be called directly from blk_dev_init(); apparently
the first step of bio merge had killed these calls but left module_init() in
these drivers under #ifdef MODULE).

loop switched to use of gendisk

swim3 switched to use of gendisk

That's a tricky one and large part of that stuff is temporary - it will be
replaced as soon as we have gendisks for all block devices and get sane
refcounting for gendisks.
	* we add per-major lists of gendisks; get_gendisk() looks into
appropriate list instead of looking through the list of all gendisks.
	* we allow driver to override that search - it can call
blk_set_probe(major, probe) and then gendisk will call probe(minor).
blk_set_probe(major, NULL) restores the default behaviour.
	* floppy.c switched to use of gendisks; we have one gendisk per
disk and let floppy_find(minor) return the right one.
	Note that final mechanism will involve a similar construction
but floppy.c is actually the least interesting application - places
where it will really play will include stuff like loading the right
high-level driver when we open /dev/hdX, etc.  And it won't be major-based...

partition_name() moved from md.c to partitions/check.c; disk_name() is not
exported anymore; partition_name() takes dev_t instead of kdev_t.

Almost all callers of add_gendisk() were immediately followed by
register_disk(disk, mk_kdev(disk->major,disk->first_minor),
	      1<<disk->minor_shift, disk->fops, something);
The only exception (DAC960.c) massaged to that form.
New helper (add_disk(disk)) introduced and aforementioned sequence
replaced with
	set_capacity(disk, something);
	add_disk(disk);

pf switched to use of gendisk and cleaned up - we pass pointers to structures
instead of minors now.

pf.c fed through lindent

beginning of macroectomy in pf.c: RR and WR macros replaced with saner
inlines a-la pcd.c

mtdblock_ro switched to use of gendisk, both mtdblock.c and mtdblock_ro.c
slightly cleaned up.

jsflash switched to use of gendisk

assorted minor cleanups

devfs-related stuff moved from cdrom.c and cdrom drivers to register_disk();
new flag (GENHD_FL_CD) marks gendisks that need such treatment.

sbpcd switched to use of gendisk

mcdx switched to use of gendisk

mcd switched to use of gendisk, failure path in module_init cleaned up

cm206 switched to use of gendisk, failure path in module_init cleaned up

cdu31a switched to use of gendisk

pcd switched to use of gendisk
