update sym2 for new IRQ API

update drivers/block for new IRQ API.

allocate FIRST_SYSTEM_VECTOR as an external interrupt. It's unlikely,
but could happen if we have a _ton_ of interrupt sources.

Found by Chuck Ebbert.

This is a patch from Robert P.J. Day that replaces www.linuxdoc.org
(which is outdated and unspported according to www.tldp.org)
with www.tldp.org in lots of Kconfig files.

Also pointed out by Al.

Al pointed out that it's unused after my last series of devfs patches.

All callers of __blk_run_queue are of the form

	spin_lock_irqsave(q->queue_lock, flags);
	__blk_run_queue(q);
	spin_unlock_irqrestore(q->queue_lock, flags);

Replace it with a blk_run_queue that does the locking itself.

In preparation of getting rid of the LOCAL_END_REQUEST mess.

split the initrd stuff out of blk.h, it's only needed in the boot code
and the ramdisk driver.

or not.

The following patches switch the few drivers that have to register
devfs entries independand of gendisks to devfs_mk_bdev.

This and the next patches switches over drivers to gendisk.devfs_name.

Previously gendisk.devfs_name was used only for partitioned devices
or CDroms, and for the latter it was slightly broken.  Fix it to
work genericly for all gendisks.

Replaces devfs_register for block devices.  Note that we do NOT pass in
an operaion vector here - it was unused in devfs_register already
and our block device code fundamentally ties the operations to the
gendisk.  There will be only very few callers of this one anyway..

Already handled by the gendisk layer.

Dasd is partitioned - all devfs stuff is handled by the gendisk layer.

Duh, ubd is partitioned.
