-What: MXSER
-When: December 2007
-Why: Old mxser driver is obsoleted by the mxser_new. Give it some time yet
- and remove it.
-Who: Jiri Slaby <jirislaby@gmail.com>

What: dev->power.power_state
When: July 2007
Why: Broken design for runtime control over driver power states, confusing
---------------------------
-What: a.out interpreter support for ELF executables
-When: 2.6.25
-Files: fs/binfmt_elf.c
-Why: Using a.out interpreters for ELF executables was a feature for
- transition from a.out to ELF. But now it is unlikely to be still
- needed anymore and removing it would simplify the hairy ELF
- loader code.
-Who: Andi Kleen <ak@suse.de>

-
What: remove EXPORT_SYMBOL(kernel_thread)
When: August 2006
Files: arch/*/kernel/*_ksyms.c
---------------------------
-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.

What: eepro100 network driver
When: January 2007
Why: replaced by the e100 driver
---------------------------
-What: USB driver API moves to EXPORT_SYMBOL_GPL
-When: February 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: vm_ops.nopage
-When: Soon, provided in-kernel callers have been converted
-Why: This interface is replaced by vm_ops.fault, but it has been around
- forever, is used by a lot of drivers, and doesn't cost much to
- maintain.
-Who: Nick Piggin <npiggin@suse.de>
-
----------------------------
-
What: PHYSDEVPATH, PHYSDEVBUS, PHYSDEVDRIVER in the uevent environment
When: October 2008
Why: The stacking of class devices makes these values misleading and
---------------------------
-What: 'time' kernel boot parameter
-When: January 2008
-Why: replaced by 'printk.time=<value>' so that printk timestamps can be
- enabled or disabled as needed
-Who: Randy Dunlap <randy.dunlap@oracle.com>
-
----------------------------
-
-What: drivers depending on OSS_OBSOLETE
-When: options in 2.6.23, code in 2.6.25
-Why: obsolete OSS drivers
-Who: Adrian Bunk <bunk@stusta.de>
-
----------------------------
-
What: libata spindown skipping and warning
When: Dec 2008
Why: Some halt(8) implementations synchronize caches for and spin
---------------------------
-What: sk98lin network driver
-When: Feburary 2008
-Why: In kernel tree version of driver is unmaintained. Sk98lin driver
- replaced by the skge driver.
-Who: Stephen Hemminger <shemminger@linux-foundation.org>
-
----------------------------
-
What: i386/x86_64 bzImage symlinks
-When: April 2008
+When: April 2010
Why: The i386/x86_64 merge provides a symlink to the old bzImage
location so not yet updated user space tools, e.g. package
---------------------------
----------------------------
-
-What: i2c-i810, i2c-prosavage and i2c-savage4
-When: May 2008
-Why: These drivers are superseded by i810fb, intelfb and savagefb.
-Who: Jean Delvare <khali@linux-fr.org>
-
----------------------------
-
-What: bcm43xx wireless network driver
-When: 2.6.26
-Files: drivers/net/wireless/bcm43xx
-Why: This driver's functionality has been replaced by the
- mac80211-based b43 and b43legacy drivers.
-Who: John W. Linville <linville@tuxdriver.com>
-
----------------------------
-
-What: ieee80211 softmac wireless networking component
-When: 2.6.26 (or after removal of bcm43xx and port of zd1211rw to mac80211)
-Files: net/ieee80211/softmac
-Why: No in-kernel drivers will depend on it any longer.
-Who: John W. Linville <linville@tuxdriver.com>
-
----------------------------
-
-What: rc80211-simple rate control algorithm for mac80211
-When: 2.6.26
-Files: net/mac80211/rc80211-simple.c
-Why: This algorithm was provided for reference but always exhibited bad
- responsiveness and performance and has some serious flaws. It has been
- replaced by rc80211-pid.
-Who: Stefano Brivio <stefano.brivio@polimi.it>
-
----------------------------
-
What (Why):
- include/linux/netfilter_ipv4/ipt_TOS.h ipt_tos.h header files
(superseded by xt_TOS/xt_tos target & match)
and slightly hurts runtime performance. Bugfixes for the old firmware
are not provided by Broadcom anymore.
Who: Michael Buesch <mb@bu3sch.de>
+
+---------------------------
+
+What: init_mm export
+When: 2.6.26
+Why: Not used in-tree. The current out-of-tree users used it to
+ work around problems in the CPA code which should be resolved
+ by now. One usecase was described to provide verification code
+ of the CPA operation. That's a good idea in general, but such
+ code / infrastructure should be in the kernel and not in some
+ out-of-tree driver.
+Who: Thomas Gleixner <tglx@linutronix.de>
+
+----------------------------
+
+What: usedac i386 kernel parameter
+When: 2.6.27
+Why: replaced by allowdac and no dac combination
+Who: Glauber Costa <gcosta@redhat.com>
+
+---------------------------
+
+What: old style serial driver for ColdFire (CONFIG_SERIAL_COLDFIRE)
+When: 2.6.28
+Why: This driver still uses the old interface and has been replaced
+ by CONFIG_SERIAL_MCF.
+Who: Sebastian Siewior <sebastian@breakpoint.cc>
+
+---------------------------
+
+What: /sys/o2cb symlink
+When: January 2010
+Why: /sys/fs/o2cb is the proper location for this information - /sys/o2cb
+ exists as a symlink for backwards compatibility for old versions of
+ ocfs2-tools. 2 years should be sufficient time to phase in new versions
+ which know to look in /sys/fs/o2cb.
+Who: ocfs2-devel@oss.oracle.com
+
+---------------------------
+
+What: SCTP_GET_PEER_ADDRS_NUM_OLD, SCTP_GET_PEER_ADDRS_OLD,
+ SCTP_GET_LOCAL_ADDRS_NUM_OLD, SCTP_GET_LOCAL_ADDRS_OLD
+When: June 2009
+Why: A newer version of the options have been introduced in 2005 that
+ removes the limitions of the old API. The sctp library has been
+ converted to use these new options at the same time. Any user
+ space app that directly uses the old options should convert to using
+ the new options.
+Who: Vlad Yasevich <vladislav.yasevich@hp.com>
+
+---------------------------
+
+What: CONFIG_THERMAL_HWMON
+When: January 2009
+Why: This option was introduced just to allow older lm-sensors userspace
+ to keep working over the upgrade to 2.6.26. At the scheduled time of
+ removal fixed lm-sensors (2.x or 3.x) should be readily available.
+Who: Rene Herman <rene.herman@gmail.com>
+
+---------------------------
+
+What: Code that is now under CONFIG_WIRELESS_EXT_SYSFS
+ (in net/core/net-sysfs.c)
+When: After the only user (hal) has seen a release with the patches
+ for enough time, probably some time in 2010.
+Why: Over 1K .text/.data size reduction, data is available in other
+ ways (ioctls)
+Who: Johannes Berg <johannes@sipsolutions.net>
+
+---------------------------
+
+What: CONFIG_NF_CT_ACCT
+When: 2.6.29
+Why: Accounting can now be enabled/disabled without kernel recompilation.
+ Currently used only to set a default value for a feature that is also
+ controlled by a kernel/module/sysfs/sysctl parameter.
