---------------------------
-What: ieee1394 core's unused exports (CONFIG_IEEE1394_EXPORT_FULL_API)
-When: January 2007
-Why: There are no projects known to use these exported symbols, except
- dfg1394 (uses one symbol whose functionality is core-internal now).

-What: ieee1394's *_oui sysfs attributes (CONFIG_IEEE1394_OUI_DB)
-When: January 2007
-Files: drivers/ieee1394/: oui.db, oui2c.sh
-Why: big size, little value

What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: December 2006
Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6
---------------------------
-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.
---------------------------
-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: Interrupt only SA_* flags
When: Januar 2007
Why: The interrupt related SA_* flags are replaced by IRQF_* to move them
---------------------------
-What: i2c-ite and i2c-algo-ite drivers
-When: September 2006
-Why: These drivers never compiled since they were added to the kernel
- tree 5 years ago. This feature removal can be reevaluated if
- someone shows interest in the drivers, fixes them and takes over
- maintenance.

-What: Bridge netfilter deferred IPv4/IPv6 output hook calling
-When: January 2007
-Why: The deferred output hooks are a layering violation causing unusual
- and broken behaviour on bridge devices. Examples of things they
- break include QoS classifation using the MARK or CLASSIFY targets,
- the IPsec policy match and connection tracking with VLANs on a
- bridge. Their only use is to enable bridge output port filtering
- within iptables with the physdev match, which can also be done by
- combining iptables and ebtables using netfilter marks. Until it
- will get removed the hook deferral is disabled by default and is
- only enabled when needed.

What: PHYSDEVPATH, PHYSDEVBUS, PHYSDEVDRIVER in the uevent environment
When: October 2008
Why: The stacking of class devices makes these values misleading and
---------------------------
+What: i2c_adapter.dev
+ i2c_adapter.list
+When: July 2007
+Why: Superfluous, given i2c_adapter.class_dev:
+ * The "dev" was a stand-in for the physical device node that legacy
+ drivers would not have; but now it's almost always present. Any
+ remaining legacy drivers must upgrade (they now trigger warnings).
+ * The "list" duplicates class device children.
+ The delay in removing this is so upgraded lm_sensors and libsensors
+ can get deployed. (Removal causes minor changes in the sysfs layout,
+ notably the location of the adapter type name and parenting the i2c
+ client hardware directly from their controller.)

+What: ACPI hooks (X86_SPEEDSTEP_CENTRINO_ACPI) in speedstep-centrino driver
+When: December 2006
+Why: Speedstep-centrino driver with ACPI hooks and acpi-cpufreq driver are
+ functionally very much similar. They talk to ACPI in same way. Only
+ difference between them is the way they do frequency transitions.
+ One uses MSRs and the other one uses IO ports. Functionaliy of
+ speedstep_centrino with ACPI hooks is now merged into acpi-cpufreq.
+ That means one common driver will support all Intel Enhanced Speedstep
+ capable CPUs. That means less confusion over name of
+ speedstep-centrino driver (with that driver supposed to be used on
+ non-centrino platforms). That means less duplication of code and
+ less maintenance effort and no possibility of these two drivers
+ going out of sync.
+ Current users of speedstep_centrino with ACPI hooks are requested to
+ switch over to acpi-cpufreq driver. speedstep-centrino will continue
+ to work using older non-ACPI static table based scheme even after this
+ date.

+What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
+When: 2.6.21
+Why: hotkey.c was an attempt to consolidate multiple drivers that use
+ ACPI to implement hotkeys. However, hotkeys are not documented
+ in the ACPI specification, so the drivers used undocumented
+ vendor-specific hooks and turned out to be more different than
+ the same.
+
+ Further, the keys and the features supplied by each platform
+ are different, so there will always be a need for
+ platform-specific drivers.
+
+ So the new plan is to delete hotkey.c and instead, work on the
+ platform specific drivers to try to make them look the same
+ to the user when they supply the same features.
+
+ hotkey.c has always depended on CONFIG_EXPERIMENTAL

+What: /sys/firmware/acpi/namespace
+When: 2.6.21
+Why: The ACPI namespace is effectively the symbol list for
+ the BIOS. The device names are completely arbitrary
+ and have no place being exposed to user-space.
+
+ For those interested in the BIOS ACPI namespace,
+ the BIOS can be extracted and disassembled with acpidump
+ and iasl as documented in the pmtools package here:

+What: ACPI procfs interface
+When: July 2007

+What: Compaq touchscreen device emulation
+When: Oct 2007
+Files: drivers/input/tsdev.c
+Why: The code says it was obsolete when it was written in 2001.
+ tslib is a userspace library which does anything tsdev can do and
+ much more besides in userspace where this code belongs. There is no
+ longer any need for tsdev and applications should have converted to
+ use tslib by now.
+ The name "tsdev" is also extremely confusing and lots of people have
+ it loaded when they don't need/use it.
