Hi,

the patchset enable CMA on Microblaze. Based on Christoph request I have
created the first patch which makes dma-continugous.h mandatory for all
archs before Microblaze wiring.

Thanks,
Michal

Changes in v2:
- New patch suggested by Christoph
- Align commit message
- Remove adding dma-contigous.h via Kbuild because it is done by previous
  patch

dma-continuguous.h is generic for all architectures except arm32 which has
its own version.

Similar change was done for msi.h by commit a1b39bae16a6
("asm-generic: Make msi.h a mandatory include/asm header")

Currently, <asm/dma-contiguous.h> is present
for only architectures that select HAVE_DMA_CONTIGUOUS.

After this commit, the other architectures will end
up with generating the unused header.

That would not be a big deal, but
it could be mentioned in the commit message?
