Andrew McRae's pcmcia/pccard code, the kernel part.

This is still very green, but I have managed to get my modem working.
Lots of work still to do, but now at least we can commit it. /phk

+ *	Slot structures for PC-CARD interface.
+ *	Each slot has a controller specific structure
+ *	attached to it. A slot number allows
+ *	mapping from the character device to the
+ *	slot structure. This is separate to the
+ *	controller slot number to allow multiple controllers
+ *	to be accessed.
