clearing both 625_CORE_CLOCK and ALTCLOCK
we first clear the latter then the final

[patch] libata: ata_piix.c PIO fix

"[libata] transfer mode cleanup" introduced bug in ata_piix.c:
previously PIO number (not mode) was passed to piix_set_piomode().
Fortunately this function is only used for (disabled) PATA support.

I bet that this is the reason why MWDMA didn't work for PATA.

Paolo Giarrusso points out that the UML merge incorrectly
caused INITIAL_JIFFIES to be reset back to zero, instead
of the debug value for getting an early jiffies wrap.

Fix it back up.

This patch fixes a problem introduced when CK804 support was added.  mmio_base can only be set in the CK804 case,
else libata will attempt to iounmap mmio_base, which isn't iomapped for the non-CK804 case.  Still need the bar 5
address, so steal from host_set->ports[0]->ioaddr.scr_addr.  Jeff, let me know if this is a bad thing to do.

Fix of the debug/trace driver and removal of irq locks.

 - Only spinlocks[bh] are used now.
 - Removed obsolete direct debug /proc interface.
 - Update of internal trace features and its API.
 - Use common definition of MAX_DESCRIPTORS.

We seem to have found an overflow problem in libata-core.c.
We were trying to DMA to the address range 0xffff8000-0xffffbfff.

In the original version of the code, given that address and
count (0xffff8000 and 0x4000), the variable "boundary" would be
set to 0, causing len to be set to 0x8000 (which is greater than
sg_len).  Then at the bottom of the loop, sg_len would be set
to 0xffffc000 (0x4000 - 0x8000), which would then cause the
loop never to terminate (until much of memory was scribbled
over or the kernel died).

The code below should be functionally identical, but not be
subject to the same overflow problem (boundary needs to be a
u33).

Some time ago, I sent on this list a mail about my strange problem with my
SiS900 network card (Subject was Sluggish performances with FreeBSD)

To sum up, when my card is in 100Mb mode, I have poor throughput but in
10Mb, all seems normal.

After some tests, it seems these results was due to a misdetection of the
PHY device.  mii-tool reports :

 product info: vendor 08:00:17, model 3 rev 0

and after some search on the web, I found it's a NS DP83847 which is very
similar.

Some interfaces (notably PCMCIA ones) don't decode the master/slave select so
you get two copies of a device appearing and bad things happening if a user
accidentally uses both. 

This checks for the model/serial matching but also knows about non ATA drives
ide=noprobe and a Maxtor problem that was found in Andrew's testing of an
earlier patch. Although M00000.. drives should be RMA'd to Maxtor (and with
info on where they were obtained...) we don't want to break anyone who has
them.

If you get invalid geometry (eg a failed drive) the box hangs on boot because
we try and unregister the registered driver and end up in a locking mess.

We change the behaviour to simply leave the device unattached which avoids
the mess.

This was put in for PPC specifically and defined in the 2.4 tree to be
paranoid about breaking stuff. The actual wait for hwif spin up is however
perfectly correct for all drives. In the normal PC case the PC BIOS has done
this but with other embedded boxes and with things like LinuxBIOS it may not
have done. Thus it should always be done.

As noticed by Alan Cox:

"It doesn't work now so it clearly isnt being used 8). We hold the lock
because its a proc function and we then replace the proc functions in the
attach method -> deadlock. It is also incredibly hard to fix without a
major rewrite."

The same is true for HDIO_SET_IDE_SCSI ioctl.

Both were broken 18 months ago in 2.5.63 as a side-effect of locking fixes.
