Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue.

Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto).

Some processors have groups of pins that aren't an even number of 16. This causes the array size calculation to under count the number of needed entries due to integer truncation. So on the BF51x, while we should have 3 bitmaps (41 / 16), we end up with 2 and pin requests for the 3rd bank end up scribbling over the top of the GPIO IRQ array.

The dma_memcpy() function takes care of flushing different caches for us. Normally this is what we want, but when resuming from mem, we don't yet have caches enabled. If these functions happen to be placed into L1 mem (which is what we're trying to relocate), then things aren't going to work. So define a non-cache dma_memcpy() variant to utilize in situations like this. Signed-off-by: NMichael Hennerich <michael.hennerich@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Anomaly 05000491 says that IFLUSH cannot have certain types of memory stalls triggered before it has completed in order to function correctly. One such condition is that it be in L1 instruction. So add a config option to move it there, default it to on, and throw up a warning when it is turned off and this anomaly exists. Since the anomaly should be worked around, we can drop the older method of calling IFLUSH multiple times.

It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.
