They only ever returned a single value.

Lots more work to do here.

bye bye icky hardcoded values.

It's now done in the static structs.

- the makefile is not the right place to describe the driver
- remove some junk

Based upon code written by NVIDIA for agpgart 2.4, forward ported and
cleaned up slightly by me. This still needs work, and is untested.

By introducing a few extra functions, we can kill off a few extra members
of the enum. More work from Christoph Hellwig.

Again from Christoph Hellwig.

From Christoph Hellwig.
(1) Kill the _setup functions - most of it can be nice, static
    structs - the few remainders are handled better elsewhere
(2) _one_ big switch in ->probe assigning these tables.

Almost 200 lOC gone and it's even readable :)

This does the following:
 - make initialization data for helper chipsets (saa7111 and saa7740)
   static and with file scope

Additionally fixes:
 - don't use irq driven i2c transfer when saa7740 is present (this screws
   up the i2c bus and may hang the computer)
 - add MODULE_DEVICE_TABLE to allow /sbin/hotplug to handle the device

Fix various places which aren't using unsigned long for jiffies.

Also other warnings and compilation errors as encountered.

Fix a bttv compile warning

The header file cleanups bite.  All these watchdog drivers need fs.h for
struct inode, struct file, etc.

- jiffies is unsigned long

- don't zero-init BSS.

Basically a mop-up of missed bits.  Also fix various warnings and compilation
errors.

teach various drivers that the CPU flags require unsigned long

All these drivers have a return hidden in a macro and I missed the lot in the
first pass due to some config option not begin set.

Update SCSI drivers for the new IRQ API.  Also fix warnings and compilation
errors as encountered.

Fix up various char drivers for the IRQ API change.  Also IDE, ISDN and i2o
bits.  Fix various warnings and compilation errors.

Mop up various block and cdrom drivers.  Also fix a bunch of warnings and
compilation failures.

Update ATM drivers to new IRQ API

Several scsi drivers are already using an IRQ_NONE.  Rename that to
SCSI_IRQ_NONE.

I found this while doing bio_map_user() changes.

Acked by Jens.

Bart did this patch, I changed it a bit. Basically it cleans the mapping
interface up a bit, and adds a little helper to set up the request from
the bio.

In addition, it fixes a long standing bug where bio_map_user() would
call blk_queue_bounce() without the direction bit being set, auch.

 - Abstract out bio request preparation
 - Have bio_map_user() set data direction (fixes bug where blk_queue_bounce()
   is called without it set)
 - Split bio_map_user() in two

So we don't have to lookup the private data everytime.

Kill one user of mem_map_reserve/mem_map_unreserve I missed the
last time and it can go away.

	PPC logics for choice of default boot device number switched to
dev_t.  Rationale: it belongs to userland; we notice partitions with
certain properties and choose one of them as the best candidate for
being a root fs; then we put the resulting device number into ROOT_DEV,
which has only one use - it's passed to mknod(2) to create a device node
on rootfs and allow mount(2) get us the final root.

	IOW, all that code has nothing whatsoever with kernel internals
of any description - the value we are generating will be passed to
mknod(2) anyway.  Switched to dev_t.

	Note: that code should eventually be moved to early userland.

	* bogus calls of invalidate_buffers() gone from floppy_open()
	* invalidate_buffers() killed.

	* new helper - __invalidate_device(bdev, do_sync).  invalidate_device()
is calling it.

	* fixed races between floppy_open()/floppy_open and
floppy_open()/set_geometry():
	a) floppy_open()/floppy_release() is done under a semaphore.  That
closes the races between simultaneous open() on /dev/fd0foo and /dev/fd0bar.
	b) pointer to struct block_device is kept as long as floppy is
opened (per-drive, non-NULL when number of openers is non-zero, does not
contribute to block_device refcount).
	c) set_geometry() grabs the same semaphore and invalidates the
devices directly instead of messing with setting fake "it had changed"
and calling __check_disk_change().

	* __check_disk_change() killed - no remaining callers
	* full_check_disk_change() killed - ditto.
