This breaks for me with:

They just need to be exported like on x86_64.
Cheers,
Mark.
Subject: [PATCH] x86: export dma_supported() and dma_set_mask() on i386
dma_supported() and dma_set_mask() were previously inlined,
but are now moved to pci-dma_32.c.
Since they're used by various drivers, they need to be
exported.
