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.

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

What:	RAW driver (CONFIG_RAW_DRIVER)
When:	December 2005
Why:	declared obsolete since kernel 2.6.3
	O_DIRECT can be used instead
Who:	Adrian Bunk <bunk@stusta.de>

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

What:	drivers that were depending on OBSOLETE_OSS_DRIVER
        (config options already removed)
When:	before 2.6.19
Why:	OSS drivers with ALSA replacements
Who:	Adrian Bunk <bunk@stusta.de>

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

What:	raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
When:	November 2006
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.
Who:	Jody McIntyre <scjody@modernduck.com>

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

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Why:	Superceded by parameter "workarounds".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.
Who:	Stefan Richter <stefanr@s5r6.in-berlin.de>

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

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.
Who:	Mauro Carvalho Chehab <mchehab@brturbo.com.br>

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

What:	remove EXPORT_SYMBOL(insert_resource)
When:	April 2006
Files:	kernel/resource.c
Why:	No modular usage in the kernel.
Who:	Adrian Bunk <bunk@stusta.de>

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

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/
Who:	Dominik Brodowski <linux@brodo.de>

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

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'.
Who:	Harald Welte <laforge@netfilter.org>

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

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
Who:	Christoph Hellwig <hch@lst.de>

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

What:	CONFIG_FORCED_INLINING
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.
Who:    Arjan van de Ven

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

What:	START_ARRAY ioctl for md
When:	July 2006
Files:	drivers/md/md.c
Why:	Not reliable by design - can fail when most needed.
	Alternatives exist
Who:	NeilBrown <neilb@suse.de>

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

What:   eepro100 network driver
When:   January 2007
Why:    replaced by the e100 driver
Who:    Adrian Bunk <bunk@stusta.de>

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

What:	pci_module_init(driver)
When:	January 2007
Why:	Is replaced by pci_register_driver(pci_driver).
Who:	Richard Knutsson <ricknu-0@student.ltu.se> and Greg Kroah-Hartman <gregkh@suse.de>

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

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.

Who:	Thomas Gleixner <tglx@linutronix.de>

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

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.)
Who:	Jean Delvare <khali@linux-fr.org>

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

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"
Who:	Arjan van de Ven <arjan@linux.intel.com>

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

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.
Who:	Christoph Hellwig <hch@lst.de>

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

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.
Who:	Greg Kroah-Hartman <gregkh@suse.de>

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

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.
Who:	Greg Kroah-Hartman <gregkh@suse.de>

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

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.
Who:	Nick Piggin <npiggin@suse.de>

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

What:	Support for the MIPS EV96100 evaluation board
When:	September 2006
Why:	Does no longer build since at least November 15, 2003, apparently
	no userbase left.
Who:	Ralf Baechle <ralf@linux-mips.org>

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

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.
Who:	Ralf Baechle <ralf@linux-mips.org>

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

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
When:	September 2006
Why:	Some do no longer build and apparently there is no user base left
	for these platforms.  Hardware out of production since several years.
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.
Who:	Ralf Baechle <ralf@linux-mips.org>

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

What:	Interrupt only SA_* flags
When:	Januar 2007
Why:	The interrupt related SA_* flags are replaced by IRQF_* to move them
	out of the signal namespace.

Who:	Thomas Gleixner <tglx@linutronix.de>
