Please be more polite to other people. After a197b59ae6 all allocations
with GFP_DMA set on nodes without ZONE_DMA fail nearly silently (only
one warning during bootup is emited, no matter how many things fail).
This is a very crude change on behaviour. To be more civil, instead of
failing emit noisy warnings each time smbd. tries to allocate a GFP_DMA
memory on non-ZONE_DMA node.

This change should be reverted after one or two major releases, but
we should be more accurate rather than hoping for the best.

Instaed of, shouldn't we revert a197b59ae6? Some arch don't have
DMA_ZONE at all.
and a197b59ae6 only care x86 embedded case. If we accept your patch, I
can imagine
other people will claim warn foold is a bug. ;)

I believe we should revert. It broke zaurus boot for metan...

Is it still a problem, or has it been fixed in the meantime?
