Re: [Linaro-mm-sig] [GIT PULL] CMA and ARM DMA-mapping updates for v3.5

I notice we have new warnings as a result of CMA being merged, though thankfully they're just in Kconfig:

warning: (ARM) selects CMA which has unmet direct dependencies (HAVE_DMA_CONTIGUOUS && HAVE_MEMBLOCK && EXPERIMENTAL)

This seems totally weird: you're mandating that ARM must have CMA selected, but it's an experimental feature? So you're implying that the entire ARM kernel becomes totally experimental for the next release cycle?

I think this needs fixing.
