-What: USER_SCHED
-When: 2.6.34
-
-Why: USER_SCHED was implemented as a proof of concept for group scheduling.
- The effect of USER_SCHED can already be achieved from userspace with
- the help of libcgroup. The removal of USER_SCHED will also simplify
- the scheduler code with the removal of one major ifdef. There are also
- issues USER_SCHED has with USER_NS. A decision was taken not to fix
- those and instead remove USER_SCHED. Also new group scheduling
- features will not be implemented for USER_SCHED.

+What: Deprecated snapshot ioctls
+When: 2.6.36
+
+Why: The ioctls in kernel/power/user.c were marked as deprecated long time
+ ago. Now they notify users about that so that they need to replace
+ their userspace. After some more time, remove them completely.

What: The ieee80211_regdom module parameter
When: March 2010 / desktop catchup
---------------------------
-What: CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information
-When: March 2010 / desktop catchup
-
-Why: The old regulatory infrastructure has been replaced with a new one
- which does not require statically defined regulatory domains. We do
- not want to keep static regulatory domains in the kernel due to the
- the dynamic nature of regulatory law and localization. We kept around
- the old static definitions for the regulatory domains of:
-
- * US
- * JP
- * EU
-
- and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
- set. We will remove this option once the standard Linux desktop catches
- up with the new userspace APIs we have implemented.

What: dev->power.power_state
When: July 2007
Why: Broken design for runtime control over driver power states, confusing

What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
-When: November 2005
+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 makes further cleanups and integration of the
+ 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/
-Who: Dominik Brodowski <linux@brodo.de>
+
+ 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.

-What: print_fn_descriptor_symbol()
-When: October 2009
-Why: The %pF vsprintf format provides the same functionality in a
- simpler way. print_fn_descriptor_symbol() is deprecated but
- still present to give out-of-tree modules time to change.

-When: February 2010
-Why: Obsoleted by the adt7475 driver.
-Who: Jean Delvare <khali@linux-fr.org>
+What: Support for lcd_switch and display_get in asus-laptop driver
+When: March 2010
+Why: These two features use non-standard interfaces. There are the
+ only features that really need multiple path to guess what's
+ the right method name on a specific laptop.
+
+ Removing them will allow to remove a lot of code an significantly
+ clean the drivers.
+
+ This will affect the backlight code which won't be able to know
+ if the backlight is on or off. The platform display file will also be
+ write only (like the one in eeepc-laptop).
+
+ This should'nt affect a lot of user because they usually know
+ when their display is on or off.

+What: capifs
+When: February 2011

+
+What: KVM memory aliases support
+When: July 2010
+Why: Memory aliasing support is used for speeding up guest vga access
+ through the vga windows.
+
+ Modern userspace no longer uses this feature, so it's just bitrotted
+ code and can be removed with no impact.

+
+What: KVM kernel-allocated memory slots
+When: July 2010
+Why: Since 2.6.25, kvm supports user-allocated memory slots, which are
+ much more flexible than kernel-allocated slots. All current userspace
+ supports the newer interface and this code can be removed with no
+ impact.
+Who: Avi Kivity <avi@redhat.com>
+
+----------------------------
+
+What: KVM paravirt mmu host support
+When: January 2011
+Why: The paravirt mmu host support is slower than non-paravirt mmu, both
+ on newer and older hardware. It is already not exposed to the guest,
+ and kept only for live migration purposes.
+Who: Avi Kivity <avi@redhat.com>

+
+What: "acpi=ht" boot option
+When: 2.6.35

+What: video4linux /dev/vtx teletext API support
+When: 2.6.35
+Files: drivers/media/video/saa5246a.c drivers/media/video/saa5249.c
+ include/linux/videotext.h
+Why: The vtx device nodes have been superseded by vbi device nodes
+ for many years. No applications exist that use the vtx support.
+ Of the two i2c drivers that actually support this API the saa5249
+ has been impossible to use for a year now and no known hardware
+ that supports this device exists. The saa5246a is theoretically
+ supported by the old mxb boards, but it never actually worked.
+
+ In summary: there is no hardware that can use this API and there
+ are no applications actually implementing this API.
+
+ The vtx support still reserves minors 192-223 and we would really
+ like to reuse those for upcoming new functionality. In the unlikely
+ event that new hardware appears that wants to use the functionality
+ provided by the vtx API, then that functionality should be build
+ around the sliced VBI API instead.
