The 8250 serial driver now has the ability to deal with the differences between the standard 8250 family of UARTs and their slightly strange brother on Alchemy SOCs. The loss of features is not considered an issue. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

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: devfs
|
|
When: July 2005
|
|
Files: fs/devfs/*, include/linux/devfs_fs*.h and assorted devfs
|
|
function calls throughout the kernel tree
|
|
Why: It has been unmaintained for a number of years, has unfixable
|
|
races, contains a naming policy within the kernel that is
|
|
against the LSB, and can be replaced by using udev.
|
|
Who: Greg Kroah-Hartman <greg@kroah.com>
|
|
|
|
---------------------------
|
|
|
|
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 depending on OBSOLETE_OSS_DRIVER
|
|
When: January 2006
|
|
Why: OSS drivers with ALSA replacements
|
|
Who: Adrian Bunk <bunk@stusta.de>
|
|
|
|
---------------------------
|
|
|
|
What: RCU API moves to EXPORT_SYMBOL_GPL
|
|
When: April 2006
|
|
Files: include/linux/rcupdate.h, kernel/rcupdate.c
|
|
Why: Outside of Linux, the only implementations of anything even
|
|
vaguely resembling RCU that I am aware of are in DYNIX/ptx,
|
|
VM/XA, Tornado, and K42. I do not expect anyone to port binary
|
|
drivers or kernel modules from any of these, since the first two
|
|
are owned by IBM and the last two are open-source research OSes.
|
|
So these will move to GPL after a grace period to allow
|
|
people, who might be using implementations that I am not aware
|
|
of, to adjust to this upcoming change.

Who: Paul E. McKenney <paulmck@us.ibm.com>
|
|
|
|
---------------------------
|
|
|
|
What: IEEE1394 Audio and Music Data Transmission Protocol driver,
|
|
Connection Management Procedures driver
|
|
When: November 2005
|
|
Files: drivers/ieee1394/{amdtp,cmp}*
|
|
Why: These are incomplete, have never worked, and are better implemented
|
|
in userland via raw1394 (see http://freebob.sourceforge.net/ for
|
|
example.)
|
|
Who: Jody McIntyre <scjody@steamballoon.com>
|
|
|
|
---------------------------
|
|
|
|
What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
|
|
When: November 2005
|
|
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@steamballoon.com>
|
|
|
|
---------------------------
|
|
|
|
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: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid
|
|
When: November 2005
|
|
Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c
|
|
Why: Match the other drivers' name for the same function, duplicate names
|
|
will be available until removal of old names.
|
|
Who: Grant Coady <gcoady@gmail.com>
|
|
|
|
---------------------------
|
|
|
|
What: remove EXPORT_SYMBOL(panic_timeout)
|
|
When: April 2006
|
|
Files: kernel/panic.c
|
|
Why: No modular usage in the kernel.
|
|
Who: Adrian Bunk <bunk@stusta.de>
|
|
|
|
---------------------------
|
|
|
|
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: EXPORT_SYMBOL(lookup_hash)
|
|
When: January 2006
|
|
Why: Too low-level interface. Use lookup_one_len or lookup_create instead.
|
|
Who: Christoph Hellwig <hch@lst.de>
|
|
|
|
---------------------------
|
|
|
|
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: au1x00_uart driver
|
|
When: January 2006
|
|
Why: The 8250 serial driver now has the ability to deal with the differences
|
|
between the standard 8250 family of UARTs and their slightly strange
|
|
brother on Alchemy SOCs. The loss of features is not considered an
|
|
issue.
