---------------------------

What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
When: 2.6.35/2.6.36
Files: drivers/pcmcia/: pcmcia_ioctl.c
Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a
normal hotpluggable bus, and with it using the default kernel
infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA
control ioctl needed by cardmgr and cardctl from pcmcia-cs is
unnecessary and potentially harmful (it does not provide for
proper locking), and makes further cleanups and integration of the
PCMCIA subsystem into the Linux kernel device driver model more
difficult. The features provided by cardmgr and cardctl are either
handled by the kernel itself now or are available in the new
pcmciautils package available at
http://kernel.org/pub/linux/utils/kernel/pcmcia/

For all architectures except ARM, the associated config symbol
has been removed from kernel 2.6.34; for ARM, it will be likely
be removed from kernel 2.6.35. The actual code will then likely
be removed from kernel 2.6.36.

This file details changes in 2.6 which affect PCMCIA card driver authors:
* pcmcia_request_io changes (as of 2.6.36)
Instead of io_req_t, drivers are now requested to fill out
struct pcmcia_device *p_dev->resource[0,1] for up to two ioport
ranges. After a call to pcmcia_request_io(), the ports found there
are reserved, after calling pcmcia_request_configuration(), they may
be used.

* No dev_info_t, no cs_types.h (as of 2.6.36)
dev_info_t and a few other typedefs are removed. No longer use them
in PCMCIA device drivers. Also, do not include pcmcia/cs_types.h, as
this file is gone.

* No dev_node_t (as of 2.6.35)
There is no more need to fill out a "dev_node_t" structure.
