* [ARM] dma: add validation of DMA paramsRussell King2008-09-292-4/+15
| | | | | | | | Validate the direction argument like x86 does. In addition, validate the dma_unmap_* parameters against those passed to dma_map_* when using the DMA bounce code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] dma: fix dmabounce dma_sync_xxx() implementationsRussell King2008-09-292-101/+69
| | | | | | | | | | | | | | | | | 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>

* [ARM] dma: provide a better dma_map_page() implementationRussell King2008-09-262-1/+23
| | | | | | | | We can translate a struct page directly to a DMA address using page_to_dma(). No need to use page_address() followed by virt_to_dma(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] Print details relevant to how we handle the cacheRussell King2008-09-251-0/+9
| | | | | | | | This replaces the original cache type decoding printks. We now indicate how we're treating the cache which we found, rather than what we found. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Introduce new bitmask based cache type macrosRussell King2008-09-252-81/+59
| | | | | | | | | | | | | | | Rather than trying to (inaccurately) decode the cache type from the registers each time we need to decide what type of cache we have, use a bitmask initialized early during boot. Since the setup is a one-off initialization, we can be a little more clever and take account of the CPU architecture as well. Note that we continue to achieve the compactness on optimised kernels by forcing tests to always-false or always-true as appropriate, thereby allowing the compiler to do build-time code elimination.

* [ARM] Remove cache type printksRussell King2008-09-251-141/+1
| | | | | | | | | | | | | | | | | | | | | | The cache type register found in ARMv5 and later CPUs changes format and meaning depending on the CPU architecture version. Currently, this code: a) doesn't work for everything - Xscale's are identified as 'unknown 5'. b) is not able to tell whether the caches are VIVT or VIPT from the cache type. c) prints rubbish on some ARMv6 and ARMv7+ CPUs. The two solutions to this are: 1. Add yet more code to decode and print the various different register formats. 2. Remove the code altogther. The code only exists to decode and print the cache parameters. Increasing the complexity of it just for the sake of a few prinks isn't worth it.

* [ARM] 5218/1: arm: improved futex supportMikael Pettersson2008-09-011-3/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux/ARM currently doesn't support robust or PI futexes. The problem is that the kernel wants to perform certain ops (cmpxchg, set, add, or, andn, xor) atomically on user-space addresses, and ARM's futex.h doesn't support that. This patch adds that support, but only for uniprocessor machines. For UP it's enough to disable preemption to ensure mutual exclusion with other software agents (futexes don't need to care about other hardware agents, fortunately). This patch is based on one posted by Khem Raj on 2007-08-01 <http://marc.info/?l=linux-arm-kernel&m=118599407413016&w=2>. (That patch is included in the -RT kernel patches.) My changes since that version include: * corrected implementation of FUTEX_OP_ANDN (must complement oparg) * added missing memory clobber to futex_atomic_cmpxchg_inatomic() * removed spinlock because it's unnecessary for UP and insufficient for SMP, instead the code is restricted to UP and relies on the fact that pagefault_disable() also disables preemption * coding style cleanups Tested on ARMv5 XScales with the glibc-2.6 nptl test suite.

| | | | | | | | | | | | | | | This patch against 2.6.27-rc3 does the following changes to FSG-3 setup code: 1) Enable RTC on FSG-3 (proper name is needed). This change is needed due to a recent change in i2c. 2) i variable is only used when compiling for big endian. So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.
