Need add generic "dma-mapping-common.h", or compiling may fail.
The related error (with allmodconfig):
CC [M] net/irda/irlan/irlan_eth.o

m32r does not provide the "common" version of the dma mapping API, so this
is certainly wrong.

But m32r really has pci.h, and also can cause this issue.
Thanks.

Oh, sorry, the reply below is incorrect, I will check it, again, thanks.
