"Coherent" means "touching DMA mappings is allowed".
Why does dma-debug complain about that?

Right, but coherency does not follow copy-on-write. The check is
there to catch cases where a page is COW'd while an active dma mapping
on the source page is present. Sure, the write is coherent, but due
to the COW it's going to the wrong page, so you are potentially
missing data in the new mapping.
See how NET_DMA inspired this check:

However with the 'cachelines-revert.patch',
related to https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/lib/dma-debug.c?id=3b7a641,
after rebooting 12 times sequentially, everything is OK!
i.e.
kernel-3.15.0-0.rc4.git0.3.fc21.i686 PASSED
