56 help
57 If you say Y here, the deprecated ioctl interface to the PCMCIA
58 subsystem will be built. It is needed by the deprecated pcmcia-cs
59 tools (cardmgr, cardctl) to function properly.
60
61 You should use the new pcmciautils package instead (see
62 <file:Documentation/Changes> for location and details).
63
64 This config option will most likely be removed from kernel 2.6.35,
65 the associated code from kernel 2.6.36.
66
67 As the PCMCIA ioctl is not locking safe, it depends on !SMP and
68 !PREEMPT.
