Fix powerpc breakage in sg chaining code

2007-10-16T20:10:58+00:00

Commit 78bdc3106a877cfa50439fa66b52acbc4e7868df ("PPC: sg chaining
support") looks to have removed some unrelated ppc code.  Lets put it
back in.

[POWERPC] Replace a few #defines with empty inline functions

[POWERPC] Fix initialization and usage of dma_mask

2007-08-10T11:04:42+00:00

powerpc has a couple of bugs in the usage of dma_masks that tend to
break when drivers explicitly try to set a 32-bit mask for example.

First, the code that generates the pci devices from the OF device-tree
doesn't initialize the mask properly, then our implementation of
set_dma_mask() was trying to validate the -previous- mask value, not the
one passed in as an argument.

This fixes these problems.

PCI: remove pci_dac_dma_... APIs

2007-07-11T23:02:11+00:00

Based on replies to a respective query, remove the pci_dac_dma_...() APIs
(except for pci_dac_dma_supported() on Alpha, where this function is used
in non-DAC PCI DMA code).

do { } while(0) is not a good imitation of function returning void;

[PATCH] Pass struct dev pointer to dma_cache_sync()

2006-12-07T16:39:41+00:00

Pass struct dev pointer to dma_cache_sync()

dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard.  Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.

[PATCH] Add struct dev pointer to dma_is_consistent()

2006-12-07T16:39:41+00:00

dma_is_consistent() is ill-designed in that it does not have a struct
device pointer argument which makes proper support for systems that consist
of a mix of coherent and non-coherent DMA devices hard.  Change
dma_is_consistent to take a struct device pointer as first argument and fix
the sole caller to pass it.
