[linux-tr] PCMCIA ifconfig down / up fix

["Mike Phillips" <phillim@amtrak.com>]

Here is the fix for the problems with the pcmcia driver not coming back up from a ifconfig down / up combination. It's a patch against 2.2.9 so includes the << 12 stuff as well.  I'm suprised this doesn't kill some isa pnp cards as well.
