2008-12-14[ARM] arch/arm/common/sa1111.c: Correct error handling codeJulia Lawall
If it is reasonable to apply PTR_ERR to the result of calling clk_get, then that result should first be tested with IS_ERR, not with !. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E,E1; @@ if ( - E == NULL + IS_ERR(E) ) { <+... when != E = E1 PTR_ERR(E) ...+> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-10-09[ARM] 5295/1: make ZONE_DMA optionalNicolas Pitre
Most ARM machines don't need a special "DMA" memory zone, and when configured out, the kernel becomes a bit smaller: | text data bss dec hex filename |3826182 102384 111700 4040266 3da64a vmlinux |3823593 101616 111700 4036909 3d992d vmlinux.nodmazone This is because the system now has only one zone total which effect is to optimize away many conditionals in page allocation paths. So let's configure this zone only on machines that need split zones. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-09-29[ARM] dma: fix dmabounce dma_sync_xxx() implementationsRussell King
The dmabounce dma_sync_xxx() implementation have been broken for quite some time; they all copy data between the DMA buffer and the CPU visible buffer no irrespective of the change of ownership. (IOW, a DMA_FROM_DEVICE mapping copies data from the DMA buffer to the CPU buffer during a call to dma_sync_single_for_device().) Fix it by getting rid of sync_single(), moving the contents into the recently created dmabounce_sync_for_xxx() functions and adjusting appropriately. This also makes it possible to properly support the DMA range sync functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-08-10[ARM] dma-mapping: improve type-safeness of DMA translationsRussell King
OMAP at least gets the return type(s) for the DMA translation functions wrong, which can lead to subtle errors.

2008-07-26dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori
Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.
