- Apply cleanup of host chip drivers by Bartomiej Zonierkiewicz:

     affected drivers - aec62xx.c, alim15x3.c, cmd64x.c, hpt34x.c, sis5513.c

     new tuning scheme (wip) part 1:
	- introduce ratemask()
	- use ata_timing_mode()
	- use ide_config_drive_speed() return value

     forward port from convert.10:
	- support for AEC6280, AEC6280R
	- misc cleanups

     I had to fix a small typo in sis5513 code...

 - Add a new entry for an old VIA cell hiding as something new.
   (Pointed out by Kees Bakker.)

 - Make the synchronization token active resident on the same level as the
   spin lock. They interact with each other.

 - Synchronize with linux-2.5.17.

 - HPT366 driver typo fix by Andries Brouwer.

 - Export udma_tcq_enable() symbol right now. The blk_get_request() is undefined
   as well.
