* locking, ARM: Annotate low level hw locks as rawThomas Gleixner2011-09-131-3/+3
| | | | | | | | | | | | Annotate the low level hardware locks which must not be preempted. In mainline this change documents the low level nature of the lock - otherwise there's no functional difference. Lockdep and Sparse checking will work as usual.

* ARM: ARM_DMA_ZONE_SIZE is no moreNicolas Pitre2011-07-181-2/+0

* ARM: change ARM_DMA_ZONE_SIZE into a variableNicolas Pitre2011-07-181-3/+6
| | | | | | | | | Having this value defined at compile time prevents multiple machines with conflicting definitions to coexist. Move it to a variable in preparation for having a per machine value selected at run time. This is relevant only when CONFIG_ZONE_DMA is selected.

* ARM: Replace platform definition of ISA_DMA_THRESHOLD/MAX_DMA_ADDRESSRussell King2011-05-121-1/+3
| | | | | | | | | | | | The values of ISA_DMA_THRESHOLD and MAX_DMA_ADDRESS are related; one is the physical/bus address, the other is the virtual address. Both need to be kept in step, so rather than having platforms define both, allow them to define a single macro which sets both of these macros appropraitely.

* ARM: 5870/1: arch/arm: Fix build failure for defconfigs without ↵Peter Hüwe2010-01-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_ISA_DMA_API set A lot of ARM-defconfigs (those without CONFIG_ISA_DMA_API set) fail to build [1][2][3] due to the changes of the patch [PATCH] PCI: Clean up build for CONFIG_PCI_QUIRKS unset by Rafael J. Wysocki (Sat, 2 Jan 2010 22:57:24 +0100) [4] as the referenced variable 'isa_dma_bridge_buggy' in asm/dma.h is enclosed by the CONFIG_ISA_DMA_API conditional all configs without this setting fail to build. I'm not sure wether moving the condition is the right way to solve the issue, but atleast it fixes the issue :) References: [1] http://kisskb.ellerman.id.au/kisskb/buildresult/1983354/ [2] http://kisskb.ellerman.id.au/kisskb/buildresult/1983333/ [3] http://kisskb.ellerman.id.au/kisskb/buildresult/1983337/ [4] http://lkml.org/lkml/2010/1/2/102 Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] Rename ISA mach/dma.h header to mach/isa-dma.hRussell King2008-11-291-1/+1

* [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-291-7/+16
| | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

* [ARM] move MAX_DMA_ADDRESS to mach/memory.hRussell King2008-11-291-0/+1
| | | | | | | Move the definition of MAX_DMA_ADDRESS from mach/dma.h to mach/memory.h, thereby placing it along side its relative, ISA_DMA_THRESHOLD. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
