[PATCH] ppc32: fix PQ2 PCI DMA interrupt handling

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

The bit position in the status register corresponding to the
PCI DMA interrupt was incorrect. Additionally, we did not
have a define for the PCI DMA interrupt.
