it821x: Add ultra_mask quirk for Vortex86SX

2009-02-02T17:53:22+00:00

commit b94b898f3107046b5c97c556e23529283ea5eadd upstream.

On Vortex86SX with IDE controller revision 0x11 ultra DMA must be
disabled. This patch was tested by DMP and seems to work.

It is a cleaned up version of their older Kernel patch:

drivers/ide/{cs5530.c,sc1200.c}: Move a dereference below a NULL test

2008-12-22T22:05:06+00:00

In each case, if the NULL test is necessary, then the dereference should be
moved below the NULL test.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// 
@@
type T;
expression E;
identifier i,fld;
statement S;
@@

- T i = E->fld;
+ T i;
  ... when != E
      when != i
  if (E == NULL) S
+ i = E->fld;
//

Fix it by removing the superfluous config option.

Revert "ide: respect current DMA setting during resume"

2008-12-08T16:42:35+00:00

This reverts commit e9eb8388306364295308132265c00bea685f409f since
it could break resume (thanks to Paul Collins for the report).

I'll look into sorting this out properly for 2.6.29
but for 2.6.28 it is the best to just revert my patch.
