smaller parport_pc for non-PCI boxes
PATCH 1/1 smaller parport_pc for non-PCI boxes
There is quite a bit of PCI stuff that gets compiled into parport_pc.c even when CONFIG_PCI isn't enabled. This patch cuts down the size quite a bit (more than 4k off the object, about 1k off the zImage) for the older non-PCI machines which are typically resource starved anyway...
Patch is against 2.4.2
Paul.

Forgot to mention that the patch also fixes the warning:
`parport_pc_superio_info' defined but not used
for non-PCI, which was the original reason why I was poking around in there.
