Need add pci.h for compiling, the related error (with allmodconfig):

I wonder whether it makes sense to include pci-dma-compat.h in
asm-generic/pci.h, I don't see why one would want the generic pci.h but
not the generic pci-dma-compat.h (cc'ing Arnd).

I think, it will let architecture guys easier to add their own
pci-dma-compat.h (although they still need generic pci_dma_compat.h, and
generic pci.h, too).

e.g. one architecture want include generic pci-dma-compat.h firstly,
then define its own features in its own pci-dma-compat.h.

Thanks.

For m32r, it also face the same issue. So I need send related patch to
asm-generic instead of arm64.

For m32r, it also face the same issue. So I need send related patch to
asm-generic instead of arm64.

I think there is no excuse for still keeping the asm-generic/pci-dma-compat.h
header around any more.

All architectures use the same implementation and have done so for years.
We should just convert the remaining users to use the dma_mapping.h
interfaces directly.

in "asm-generic/pci-dma-compat.h", it include "linux/dma-mapping.h" firstly.

So can we say it also has additional features (at least for compatible
old things) which "dma-mapping.h" not have ?

Thanks.
