Sorry, I didn't realize that this email ended up in my spam folder,
and I just saw it today.

I am considering directly selecting `HAVE_DMA_CONTIGUOUS`,
but another possibility is to make it depend on `DMA_CMA`.
Can anyone advise which approach would be better?
If there are no objections, I plan to send a patch on Monday:
select `HAVE_DMA_CONTIGUOUS`
