-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: old NCR53C9x driver
When: October 2007
Why: Replaced by the much better esp_scsi driver. Actual low-level
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.

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.

+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

What: drivers depending on OSS_OBSOLETE
When: options in 2.6.23, code in 2.6.25
Why: obsolete OSS drivers

+
+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.

+
+---------------------------
+
+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.
