-What: /sys/devices/.../power/state
- dev->power.power_state
- dpm_runtime_{suspend,resume)()
+What: dev->power.power_state
When: July 2007
Why: Broken design for runtime control over driver power states, confusing
driver-internal runtime power management with: mechanisms to support
---------------------------
-What: RAW driver (CONFIG_RAW_DRIVER)
-When: December 2005
-Why: declared obsolete since kernel 2.6.3
- O_DIRECT can be used instead

-
----------------------------
-
-What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
-When: June 2007
-Why: Deprecated in favour of the more efficient and robust rawiso interface.
- Affected are applications which use the deprecated part of libraw1394
- (raw1394_iso_write, raw1394_start_iso_write, raw1394_start_iso_rcv,
- raw1394_stop_iso_rcv) or bypass libraw1394.

What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: December 2006
Files: include/linux/video_decoder.h
+Check: include/linux/video_decoder.h
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
What: remove EXPORT_SYMBOL(kernel_thread)
When: August 2006
Files: arch/*/kernel/*_ksyms.c
-Funcs: kernel_thread
+Check: kernel_thread
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
---------------------------
-What: drivers depending on OSS_OBSOLETE_DRIVER
-When: options in 2.6.20, code in 2.6.22
-Why: OSS drivers with ALSA replacements
-Who: Adrian Bunk <bunk@stusta.de>
-
----------------------------
-
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: 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: Interrupt only SA_* flags
When: September 2007
Why: The interrupt related SA_* flags are replaced by IRQF_* to move them
---------------------------
- What: i2c-isa
- When: December 2006
- Why: i2c-isa is a non-sense and doesn't fit in the device driver
- model. Drivers relying on it are better implemented as platform
- drivers.
- Who: Jean Delvare <khali@linux-fr.org>
-
- ---------------------------
-
What: i2c_adapter.list
When: July 2007
Why: Superfluous, this list duplicates the one maintained by the driver
---------------------------
-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.

- replaced by the skge driver.

-
What: Compaq touchscreen device emulation
When: Oct 2007
Files: drivers/input/tsdev.c
---------------------------
-What: Multipath cached routing support in ipv4
-When: in 2.6.23
-Why: Code was merged, then submitter immediately disappeared leaving
- us with no maintainer and lots of bugs. The code should not have
- been merged in the first place, and many aspects of it's
- implementation are blocking more critical core networking
- development. It's marked EXPERIMENTAL and no distribution
- enables it because it cause obscure crashes due to unfixable bugs
- (interfaces don't return errors so memory allocation can't be
- handled, calling contexts of these interfaces make handling
- errors impossible too because they get called after we've
- totally commited to creating a route object, for example).
- This problem has existed for years and no forward progress
- has ever been made, and nobody steps up to try and salvage
- this code, so we're going to finally just get rid of it.

+What: 'time' kernel boot parameter
+When: January 2008
+Why: replaced by 'printk.time=<value>' so that printk timestamps can be

+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
---------------------------
+What: Legacy RTC drivers (under drivers/i2c/chips)
+When: November 2007
+Why: Obsolete. We have a RTC subsystem with better drivers.
+Who: Jean Delvare <khali@linux-fr.org>
+
+---------------------------
+
+What: iptables SAME target
+When: 1.1. 2008
+Files: net/ipv4/netfilter/ipt_SAME.c, include/linux/netfilter_ipv4/ipt_SAME.h
+Why: Obsolete for multiple years now, NAT core provides the same behaviour.
+ Unfixable broken wrt. 32/64 bit cleanness.
+Who: Patrick McHardy <kaber@trash.net>
+
+---------------------------
+
+What: The arch/ppc and include/asm-ppc directories
+When: Jun 2008
+Why: The arch/powerpc tree is the merged architecture for ppc32 and ppc64
+ platforms. Currently there are efforts underway to port the remaining
+ arch/ppc platforms to the merged tree. New submissions to the arch/ppc
+ tree have been frozen with the 2.6.22 kernel release and that tree will
+ remain in bug-fix only mode until its scheduled removal. Platforms
+ that are not ported by June 2008 will be removed due to the lack of an
+ interested maintainer.
+Who: linuxppc-dev@ozlabs.org
+
+---------------------------
+
+What: mthca driver's MSI support
+When: January 2008
+Files: drivers/infiniband/hw/mthca/*.[ch]
+Why: All mthca hardware also supports MSI-X, which provides
+ strictly more functionality than MSI. So there is no point in
+ having both MSI-X and MSI support in the driver.
