ARM/dma-mapping: use dma-direct unconditionally Use dma-direct unconditionally on arm. It has already been used for some time for LPAE and nommu configurations. This mostly changes the streaming mapping implementation and the (simple) coherent allocator for device that are DMA coherent. The existing complex allocator for uncached mappings for non-coherent devices is still used as is using the arch_dma_alloc/arch_dma_free hooks.

dma-mapping: split <linux/dma-mapping.h> Split out all the bits that are purely for dma_map_ops implementations and related code into a new <linux/dma-map-ops.h> header so that they don't get pulled into all the drivers. That also means the architecture specific <asm/dma-mapping.h> is not pulled in by <linux/dma-mapping.h> any more, which leads to a missing includes that were pulled in by the x86 or arm versions in a few not overly portable drivers.

ARM: migrate to common PSCI client code Now that the common PSCI client code has been factored out to drivers/firmware, and made safe for 32-bit use, move the 32-bit ARM code over to it. This results in a moderate reduction of duplicated lines, and will prevent further duplication as the PSCI client code is updated for PSCI 1.0 and beyond. The two legacy platform users of the PSCI invocation code are updated to account for interface changes. In both cases the power state parameter (which is constant) is now generated using macros, so that the pack/unpack logic can be killed in preparation for PSCI 1.0 power state changes.

ARM: make arrays containing machine compatible strings const The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.

You should be able to just call l2x0_of_init > unconditionally. The condition was really to just avoid the smc on > Midway which does get handled on h/w, but not if running virtualized.

Flush is done implicitly inside of l2x0_disable(). But some SoC's override default .disable handler and don't flush cache. This may lead to a corrupted memory during Kexec reboot on these platforms.

ARM: highbank: convert to twd_local_timer_register() interface Add support for the new smp_twd runtime registration interface to the highbank platforms, and remove the old compile-time support. The highbank DTS file is updated to match the TWD DT documentation and fixes the timer trigger (rising edge).

ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMP It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

ARM: highbank: remove incorrect BSYM usage BSYM macro is only needed for assembly files and its usage in c files is wrong, so remove it. The linker will correctly set bit 0 for Thumb2 kernels. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Dave Martin <dave.martin@linaro.org>
