The patch that you distributed had a couple of errors in compiling, namely:

  CC [M]  drivers/ssb/driver_pcicore.o
drivers/ssb/driver_pcicore.c: In function ‘ssb_pcie_mdio_set_block’:
drivers/ssb/driver_pcicore.c:457:7: error: ‘i’ undeclared (first use in this
function)
drivers/ssb/driver_pcicore.c:457:7: note: each undeclared identifier is reported
only once for each function it appears in
drivers/ssb/driver_pcicore.c: In function ‘ssb_pcie_mdio_read’:
drivers/ssb/driver_pcicore.c:503:2: error: expected ‘;’ before ‘pcicore_write32’
make[2]: *** [drivers/ssb/driver_pcicore.o] Error 1
make[1]: *** [drivers/ssb] Error 2
make[1]: *** Waiting for unfinished jobs....

Did you forget a quilt refresh?

My machine does not have the DMA error, but I will be testing.
