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.
