/proc/pid/oom_adj was deprecated in August 2010 with the introduction of
the new oom killer heuristic.
This patch copies the Documentation/feature-removal-schedule.txt entry for
this tunable to the Documentation/ABI/obsolete directory so nobody misses
it.

The drivers
- ohci1394 (controller driver)
- ieee1394 (core)
- dv1394, raw1394, video1394 (userspace ABI)
- eth1394, sbp2 (protocol drivers)
are replaced by
- firewire-ohci (controller driver)
- firewire-core (core and userspace ABI)
- firewire-net, firewire-sbp2 (protocol drivers)
which are more featureful, better performing, and more secure than the older
drivers; all with a smaller and more modern code base.
The driver firedtv in drivers/media/dvb/firewire/ contains backends to both
ieee1394 and firewire-core. Its ieee1394 backend code can be removed in an
independent commit; firedtv as-is builds and works fine without ieee1394.
The driver pcilynx (an incomplete controller driver) is deleted without
replacement since PCILynx cards are extremely rare. Owners of these cards
use them with the stand-alone bus sniffer driver nosy instead.
The drivers nosy and init_ohci1394_dma which do not interact with either of
the two IEEE 1394 stacks are not affected by the ieee1394 subsystem removal.
There are still some issues with the newer firewire subsystem compared to
the older one:
- The rare and quirky controllers ALi M52xx, Apple UniNorth v1, NVIDIA
NForce2 are even less well supported by firewire-ohci than by ohci1394.
I am looking into the M52xx issue.
- The experimental firewire-net is reportedly less stable than its
experimental cousin eth1394.
- Audio playback of a certain group of audio devices (ones based on DICE
chipset with EAP; supported by prerelease FFADO code) does not work yet.
This issue is still under investigation.
- There were some ieee1394 based out-of-the-mainline drivers. Of them,
only lisight, an audio driver for iSight webcams, seems still useful.
Work is underway to reimplement it on top of firewire-core.
All these remainig issues are minor; they should not stand in the way of
overall better user experience of IEEE 1394 on Linux, together with a
reduction in support efforts and maintenance burden. The coexistence of two
IEEE 1394 kernel driver stacks in the mainline since 2.6.22 shall end now,
as announced earlier this year.

This patch (as1367) deprecates USB's power/level sysfs attribute in
favor of the power/control attribute provided by the runtime PM core.
The two attributes do the same thing.
It would be nice to replace power/level with a symlink to
power/control, but at the moment sysfs doesn't offer any way to do so.

This moves sysfs ABI info from Documentation/rfkill.txt to the
ABI subfolder and reformats it.
This also schedules the deprecated sysfs parts to be removed in
2012 (claim file) and 2014 (state file).

/sys/fs is where we really want file system specific sysfs objects.
Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain
backwards compatibility with old ocfs2-tools by using a sysfs symlink. After
some time (2 years), the symlink can be safely removed. This patch also adds
documentation to make it easier for people to figure out what /sys/fs/o2cb
is used for.

Nobody ported ffmpeg from dv1394 to rawiso yet, and there is no
justification to remove dv1394 right now.
Nevertheless, a strong deprecation of this ABI makes a lot of sense,
especially as Kristian H's drivers shape up to be an attractive
alternative to the existing ones. But we don't have a schedule at the
moment.
