Add enough arch-specific compat signals code to enable parisc64 to compile and boot out of the mainline tree. There are likely still many dragons here, but this is a start to squashing the last big difference between the mainline tree and the parisc-linux tree. The remaining bugs can be squashed as they come up. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
