siimage: PIO1/2 taskfile transfer overclocking fix

2007-04-08T23:16:18+00:00

Fix two typos found by SiI680A documentation check.  They caused the taskfile
transfer overclocking:

- in PIO mode 1 as 0x2283 must be used for both data and taskfile transfers;

- in PIO mode 2 as data and taskfile timings are swapped when writing to the
  MMIO regs.

Fix coding style and trailing whitespace in enclosing statements while at it...

ide-floppy: Fix unformatted media crash

2007-04-04T19:34:22+00:00

A ZIP or similar with unformatted media will cause crashes when attempts
are made to read/write it in some cases. This is because bs_factor is
zero and we divide by it causing an oops.

As the size of a non-accessible/non-existant media is really a bit of a
zen question it doesn't matter if non-existant media is 512 bytes per
sector or zero. Setting it to 1 causes us to generate 512 bytes/sector
accesses and error properly.

Based on a fix found lurking in an ancient bugzilla entry since about 2004 (ugghhh)

atiixp: hang fix

2007-01-22T20:41:23+00:00

When the old IDE layer calls into methods in the driver during error
handling it is essentially random whether ide_lock is already held.  This
causes a deadlock in the atiixp driver which also uses ide_lock internally
for locking.

Switch to a private lock instead.

alim15x3.c: M5229 (rev c8) support for DMA cd-writer

2006-12-04T13:24:41+00:00

Configuration bits are not set properly for DMA on some chipset revisions.
It has already been corrected for M5229 (rev c7) but not for M5229 (rev
c8).  This leads to the bug described at
http://bugzilla.kernel.org/show_bug.cgi?id=5786 (lost interrupt + ide bus
hangs).

sgiioc4: Disable module unload

2006-11-29T13:22:11+00:00

This patch removes a module_exit function that sgiioc4 should not have had.

It seems that the IDE layer doesn't support submodule unloading. sgiioc4
was the only driver in drivers/ide/pci that had an exit function.
After an unload, the devices would stay around and the next attempt to
reference would crash...

Old IDE, fix SATA detection for cabling

2006-11-20T21:30:21+00:00

This patch is identical to that introduced in
1a1276e7b6cba549553285f74e87f702bfff6fac to the Linus' 2.6 development tree
by Alan Cox.

'This is based on the proposed patches flying around but also checks that
the device in question is new enough to have word 93 rather thanb blindly
assuming word 93 == 0 means SATA (see ATA-5, ATA-7)' -- Alan Cox

Required for my SATA drive on an Asus Pundit-R to operate above 33MBps.
