| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 45c79433c02b8fe7b8a1cbf60548a9798d0502ed got things building but then commit 17d2f877ae8b68b09bf88a9949ee64fbbda5ee10 and others where merged in from a seperate tree and this has resulted from a build failure due to the redefinition of IRQ_EINT(). Fix this by merging a new commit. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| | * ARM: S5P: Fix the platform external interrupt issues.Pannaga Bhushan2010-05-268-28/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does the following: 1. Corrects the common platform code for external interrupts for using the VIC mask/unmask bits also. 2. Moves the common defines related to external interrupt for plat-s5p to common files. 3. Based on the new common defines, corresponding changes are made in the affected platforms (S5P6440, S5P6442 and S5PC100).

Guard the new implementation with a new config option: CONFIG_USE_PERCPU_NUMA_NODE_ID. Archs which support this new implemention will default this option to 'y' when NUMA is configured. This config option could be removed if/when all archs switch over to the generic percpu implementation of numa_node_id(). Arch support involves: 1) converting any existing per cpu variable implementations to use this implementation. x86_64 is an instance of such an arch. 2) archs that don't use a per cpu variable for numa_node_id() will need to initialize the new per cpu variable "numa_node" as cpus are brought on-line. ia64 is an example. 3) Defining USE_PERCPU_NUMA_NODE_ID in arch dependent Kconfig--e.g., when NUMA is configured. This is required because I have retained the old implementation by default to allow archs to be modified incrementally, as desired. Subsequent patches will convert x86_64 and ia64 to use this implemenation.

* | | asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()FUJITA Tomonori2010-05-275-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are only two ways to define sg_dma_len(); use sg->dma_length or sg->length. This patch introduces NEED_SG_DMA_LENGTH that enables architectures to choose sg->dma_length or sg->length.

* | | asm-generic: remove ISA_DMA_THRESHOLD in scatterlist.hFUJITA Tomonori2010-05-274-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first half of the attempt to use asm-generic/scatterlist.h on every architecture. There are only two ways to define scatterlist structure. So it's easy to convert every architecture to use asm-generic/scatterlist.h. This patch: The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work for powerpc. This lets architectures defin ISA_DMA_THRESHOLD. Hopefully, we can remove ISA_DMA_THRESHOLD in the future; we can do better to decide if the bouncing is necessary or not.

Fixed shift of the given offset, to open the maintenance window 2. Mask offset to limit access to the opened maintenance window 3. Added extended destid part to rowtear register, required for 16bit mode This method is matching maintenance transactions generation described by Freescale in the appnote AN2932. With this modification full access to a 16MB maintenance window is possible, this patch is required for IDT cps switches. For easier handling of the access routines, the access was limited to aligned memory regions. This should be no problem because all registers are 32bit wide.
