2) ARCH_DMA_MINALIGN
2) ARCH_KMALLOC_MINALIGN

Architectures must ensure that kmalloc'ed buffer is
DMA-safe. Drivers and subsystems depend on it. If an architecture
isn't fully DMA-coherent (i.e. hardware doesn't ensure that data in
the CPU cache is identical to data in main memory),
ARCH_DMA_MINALIGN must be set so that the memory allocator
ARCH_KMALLOC_MINALIGN must be set so that the memory allocator
makes sure that kmalloc'ed buffer doesn't share a cache line with
the others. See arch/arm/include/asm/cache.h as an example.

Note that ARCH_DMA_MINALIGN is about DMA memory alignment
Note that ARCH_KMALLOC_MINALIGN is about DMA memory alignment
constraints. You don't need to worry about the architecture data
alignment constraints (e.g. the alignment constraints about 64-bit
objects).

3) Supporting multiple types of IOMMUs

If your architecture needs to support multiple types of IOMMUs, you
can use include/linux/asm-generic/dma-mapping-common.h. It's a
library to support the DMA API with multiple types of IOMMUs. Lots
of architectures (x86, powerpc, sh, alpha, ia64, microblaze and
sparc) use it. Choose one to see how it can be used. If you need to
support multiple types of IOMMUs in a single system, the example of
x86 or powerpc helps.

carrier reports. Trying to disable wide band receiver while carrier

If your description starts to get long, that's a sign that you probably
need to split up your patch. See #3, next.

When you submit or resubmit a patch or patch series, include the
complete patch description and justification for it. Don't just
say that this is version N of the patch (series). Don't expect the
patch merger to refer back to earlier patch versions or referenced
URLs to find the patch description and put that into the patch.
I.e., the patch (series) and its description should be self-contained.
This benefits both the patch merger(s) and reviewers. Some reviewers
probably didn't even receive earlier versions of the patch.

If the patch fixes a logged bug entry, refer to that bug entry by
number and URL.
