I got a build error with this version, and had to remove the #include
<byteorder.h> line.

After that, I get the following build warnings:
CC [M] drivers/staging/altpciechdma/altpciechdma.o
drivers/staging/altpciechdma/altpciechdma.c: In function âdma_testâ:
drivers/staging/altpciechdma/altpciechdma.c:541: warning: cast from pointer to integer of different size

drivers/staging/altpciechdma/altpciechdma.c: At top level:
drivers/staging/altpciechdma/altpciechdma.c:416: warning: âape_sg_to_chdma_tableâ defined but not used

Also, sparse spits out a lot of warnings as well.

Care to send me a follow-on patch to fix these up?
