ataflop.c switched to use of gendisks

amiflop.c switched to use of gendisks

macroectomy a-la pf.c and pcd.c ones, ditto for passing pointers to
structures instead of minors.

pd.c fed through Lindent

dumb expansion of macro - it had #define CURRENT current_req

tapeblock never assignes anything to its elements of blk_size[][]; we could
not bother allocating it in the first place.

More trivial fixes: typos in partitions/check.c, block/floppy.c and
acorn/block/fd1772.c + replacement of #define with inline in block/floppy.c
(fd_eject()).

Some trivial fixes for some typos introduced by Al's gendisk changes..

 - missing comma in cdu31a
 - missing semicolon in cdu31a
 - comma instead of colon in gscd
 - semicolon instead of comma in mcd
 - missing closing bracket in sonycd535

From Andries.

From davem: replace `unsigned' with size_t.

floppies and CD's in /proc/partitions.

Some idiot (OK, it was me) broke free_area_init_node for
non discontigmem systems that call it directly (eg sparc64),
during a recent cleanup, thus invoking the wrath of DaveM.

I know Dave sent you a patch yesterday, but I think the BUG
statement in it will break anyone who just uses free_area_init
(eg any PC). So here's a portion of Dave's patch that should
fix things for everyone I think. Unfortunately my non-NUMA
test box is borked right now, but it just removes the BUG
statement from what he tested, and it's so simple that even
I couldn't screw this up (famous last words).

This code really needs some more cleanup work, but this will
fix it for now so everyone can do their work ...

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).

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);
