  The following is a list of files and features that are going to be
  removed in the kernel source tree.  Every entry should contain what
  exactly is going away, why it is happening, and who is going to be doing
  the work.  When the feature is removed from the kernel, it should also
  be removed from this file.

  Why:	Deprecated in favour of the new ioctl-based rawiso interface, which is
  	more efficient.  You should really be using libraw1394 for raw1394
  	access anyway.

  What:	sbp2: module parameter "force_inquiry_hack"
  When:	July 2006
  Why:	Superceded by parameter "workarounds". Both parameters are meant to be
  	used ad-hoc and for single devices only, i.e. not in modprobe.conf,
  	therefore the impact of this feature replacement should be low.

  What:	Video4Linux API 1 ioctls and video_decoder.h from Video devices.
  When:	July 2006
  Why:	V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6
  	series. The old API have lots of drawbacks and don't provide enough
  	means to work with all video and audio standards. The newer API is
  	already available on the main drivers and should be used instead.
  	Newer drivers should use v4l_compat_translate_ioctl function to handle
  	old calls, replacing to newer ones.
  	Decoder iocts are using internally to allow video drivers to
  	communicate with video decoders. This should also be improved to allow
  	V4L2 calls being translated into compatible internal ioctls.

  What:	PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
  When:	November 2005
  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 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/

  What:	ip_queue and ip6_queue (old ipv4-only and ipv6-only netfilter queue)
  When:	December 2005
  Why:	This interface has been obsoleted by the new layer3-independent
  	"nfnetlink_queue".  The Kernel interface is compatible, so the old
  	ip[6]tables "QUEUE" targets still work and will transparently handle
  	all packets into nfnetlink queue number 0.  Userspace users will have
  	to link against API-compatible library on top of libnfnetlink_queue 
  	instead of the current 'libipq'.

  What:	remove EXPORT_SYMBOL(kernel_thread)
  When:	August 2006
  Files:	arch/*/kernel/*_ksyms.c
  Why:	kernel_thread is a low-level implementation detail.  Drivers should
          use the <linux/kthread.h> API instead which shields them from
  	implementation details and provides a higherlevel interface that
  	prevents bugs and code duplication

  When:	June 2006
  Why:	Config option is there to see if gcc is good enough. (in january
          2006). If it is, the behavior should just be the default. If it's not,
  	the option should just go away entirely.

  What:	Usage of invalid timevals in setitimer
  When:	March 2007
  Why:	POSIX requires to validate timevals in the setitimer call. This
  	was never done by Linux. The invalid (e.g. negative timevals) were
  	silently converted to more or less random timeouts and intervals.
  	Until the removal a per boot limited number of warnings is printed
  	and the timevals are sanitized.

  What:	I2C interface of the it87 driver
  When:	January 2007
  Why:	The ISA interface is faster and should be always available. The I2C
  	probing is also known to cause trouble in at least one case (see
  	bug #5889.)

  What:	Unused EXPORT_SYMBOL/EXPORT_SYMBOL_GPL exports
  	(temporary transition config option provided until then)
  	The transition config option will also be removed at the same time.
  When:	before 2.6.19
  Why:	Unused symbols are both increasing the size of the kernel binary
  	and are often a sign of "wrong API"

  What:	remove EXPORT_SYMBOL(tasklist_lock)
  When:	August 2006
  Files:	kernel/fork.c
  Why:	tasklist_lock protects the kernel internal task list.  Modules have
  	no business looking at it, and all instances in drivers have been due
  	to use of too-lowlevel APIs.  Having this symbol exported prevents
  	moving to more scalable locking schemes for the task list.

168
  What:	mount/umount uevents
  When:	February 2007
  Why:	These events are not correct, and do not properly let userspace know
  	when a file system has been mounted or unmounted.  Userspace should
  	poll the /proc/mounts file instead to detect this properly.

  What:	USB driver API moves to EXPORT_SYMBOL_GPL
  When:	Febuary 2008
  Files:	include/linux/usb.h, drivers/usb/core/driver.c
  Why:	The USB subsystem has changed a lot over time, and it has been
  	possible to create userspace USB drivers using usbfs/libusb/gadgetfs
  	that operate as fast as the USB bus allows.  Because of this, the USB
  	subsystem will not be allowing closed source kernel drivers to
  	register with it, after this grace period is over.  If anyone needs
  	any help in converting their closed source drivers over to use the
  	userspace filesystems, please contact the
  	linux-usb-devel@lists.sourceforge.net mailing list, and the developers
  	there will be glad to help you out.

  What:	find_trylock_page
  When:	January 2007
  Why:	The interface no longer has any callers left in the kernel. It
  	is an odd interface (compared with other find_*_page functions), in
  	that it does not take a refcount to the page, only the page lock.
  	It should be replaced with find_get_page or find_lock_page if possible.
  	This feature removal can be reevaluated if users of the interface
  	cannot cleanly use something else.

  ---------------------------
  
  What:	Support for the Momentum / PMC-Sierra Jaguar ATX evaluation board
  When:	September 2006
  Why:	Does no longer build since quite some time, and was never popular,
  	due to the platform being replaced by successor models.  Apparently
  	no user base left.  It also is one of the last users of
  	WANT_PAGE_VIRTUAL.

  ---------------------------
  
  What:	Support for the Momentum Ocelot, Ocelot 3, Ocelot C and Ocelot G
  When:	September 2006
  Why:	Some do no longer build and apparently there is no user base left
  	for these platforms.
  Who:	Ralf Baechle <ralf@linux-mips.org>

  What:	Support for MIPS Technologies' Altas and SEAD evaluation board

  Who:	Ralf Baechle <ralf@linux-mips.org>
  
  ---------------------------
  
  What:	Support for the IT8172-based platforms, ITE 8172G and Globespan IVR
  When:	September 2006
  Why:	Code does no longer build since at least 2.6.0,  apparently there is
  	no user base left for these platforms.  Hardware out of production
  	since several years and hardly a trace of the manufacturer left on
  	the net.
