[PATCH] pcmcia: add a config option for the PCMICA ioctl
Add a new config option to control the building of the PCMCIA IOCTL. Currently,
it is not yet made public, though the help text is there already.

Say Y here if you want to attach PCMCIA- or PC-cards to your Linux

- and the newer 32 bit CardBus cards.

PC-cards are such 16-bit PCMCIA cards, so unless you know you're
only using 32-bit CardBus cards, say Y or M here.
- To use 16-bit PCMCIA cards, you will need supporting software from
- David Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
- for location). Please also read the PCMCIA-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
