Now that the devicemapper hit the tree there's no more reason
to keep the uncompiling LVM1 code around and it's various hacks
to other files around, this patch removes it.

	* first application of the fact that block device methods are
per-disk and not per-major - IDE subdrivers got block_device_operations
of their own, redirects in ide.c are gone, so is a bunch of methods of
IDE subdrivers.

	* ide_..._ioctl() never use two of five arguments - inode and file.
Arguments removed.

	This chunk and the next one basically do equivalent of sard in the
right way - counters are exported per-disk in driverfs, as attributes of
disk or partition nodes.

	* do_open() cleaned up
	* we always pick block_device_operations from gendisk->fops now
	* register_blkdev() just stores the name of driver, nothing more
	* ->bd_op and ->bd_queue removed - we have that in gendisk
	* get_blkfops() is gone

	* we move allocation of gendisks in ide-probe to the moment when
queues are set up, so everything that wants to feed requests in one of
IDE queues can safely set ->rq_disk

	* per-major array eliminated, every disk is a separate source of
randomness

	* remove blk_dev[]
	* removed BLK_DEFAULT_QUEUE
	* moved definition of CURRENT into drivers that used it
	* removed definition of QUEUE from headers

	* compile fixes
	* switched to private queue
	* set ->queue

	* killed uses of CURRENT and QUEUE

	* switched to private queues
	* set ->queue

	* killed remaining CURRENT

	* switched to private queues
	* set ->queue and ->private_data
	* switched to use of ->bd_disk and ->rq_disk
	* cleaned up

	* switched to private queues
	* set ->queue and ->private_data
	* switched to use of ->bd_disk and ->rq_disk
	* folded recalibrate[] and special_op[] into hd_info[]
	* switched to passing pointers instead of indices
	* cleaned up

	* switched to private queues
	* set ->queue

	* switched to private queues

	* switched to use of ->bd_disk and ->rq_disk
	* fixed the problem with request_module() from open()
	* cleaned up

I missed sparc64 when I broke up read_barrier_depends in -mm and sent
to Linus.  Please apply this to your tree until Linus is back and I can
fix it.
