[PATCH] 2.5.24 IDE 95

I have Martin's permission to push some ide-clean patches, so here we go.

I'm running fine SMP kernel with spinlocks debugging enabled on UP.
Note that this patch brokes ide-cd/tape/floppy/scsi locking...

This patch is mainly for developers to have something to sync with... ;-)

still TODO:
- remove ide_wait commands from interrupt paths
- move locking/completion upwards from ide_do_drive_cmd()
- fix ide device setup/tear down locking
- locking of ioctls
- tape->spinlock is probably obsolete now

It is a merge of patches by Alexander Atanasov and Zwane Mwaikambo
(big thanks guys!) plus some corrections by me...

- Remove locking from IRQ handlers (*_intr etc.) and ata_ops->do_reqeuest(),

- Add non-locking __blk_get_request() and __blk_attempt_remege() helpers
  to block layer (ll_rw_blk.c).

- Move locking up to the entry points.

- Move ata_expiry_t functions to the ide_startstop_t interface
  (need to call ata_error, and its return is idestartstop_t, not wait time).

- Kill ata_end_request() and restart_request() (they were locking variants).

- Disable some ide__sti() for now.

- Misc fixes.
