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.

A specialised HID driver for the Creative Prodikeys PC-MIDI USB Keyboard.
The Prodikeys PC-MIDI is a multifunction keyboard comprising a qwerty keyboard,
multimedia keys and a touch sensitive musical keyboard.
The specialised HID driver adds full support for the musical keyboard and extra
multimedia keys which are not currently handled by the default HID driver.
The specialised HID driver interfaces with ALSA, and presents the midi keyboard
as a rawmidi device. Sustain duration, octave shifting and the midi output
channel can be read/written form userspace via sysfs.

This Patch adds support for Kone gaming mouse from Roccat.
It provides access to profiles, settings, firmware, weight,
actual settings etc. through sysfs attributes.
Event handling of this mouse differs from standard hid behaviour
in that tilt button press is reported in each move event which
results in strange behaviour if not handled by the driver.
This is a heavily reworked version of the previously introduced driver.
The changes include most of the previously raised concerns,
memory leak and other fixes, code cleanups, adoption of additional
achieved knowlege about the hardware and is (IMHO) a much better version
than before even when I exchanged reduced USB-IO with a bigger memory
consumption.
I refused to implement one mentioned point:
Removing the 'just-because-we-can' attributes. Motivation:
Reading the clipped in weight: I'm no gamer and can't determine the
usefulness of this feature but if the manufacturer implements such a
feature it might make sense to someone and I would unwillingly limit the
functionality besides its such a small feature.
Reading the actual profile and dpi settings: Here I can testify that one
can get lost of the actual settings when switching back and forth.
The manufacturers windows driver has the ability for on-screen-display
of the values and there is a mouse in the market that has an lcd on the
underside of it to show these values. So I think this feature makes sense
not only for me and shouldn't be removed.

This is a simpler, gentler variant of memory_failure() for soft page
offlining controlled from user space. It doesn't kill anything, just
tries to invalidate and if that doesn't work migrate the
page away.
This is useful for predictive failure analysis, where a page has
a high rate of corrected errors, but hasn't gone bad yet. Instead
it can be offlined early and avoided.
The offlining is controlled from sysfs, including a new generic
entry point for hard page offlining for symmetry too.
We use the page isolate facility to prevent re-allocation
race. Normally this is only used by memory hotplug. To avoid
races with memory allocation I am using lock_system_sleep().
This avoids the situation where memory hotplug is about
to isolate a page range and then hwpoison undoes that work.
This is a big hammer currently, but the simplest solution
currently.
When the page is not free or LRU we try to free pages
from slab and other caches. The slab freeing is currently
quite dumb and does not try to focus on the specific slab
cache which might own the page. This could be potentially
improved later.
Thanks to Fengguang Wu and Haicheng Li for some fixes.
[Added fix from Andrew Morton to adapt to new migrate_pages prototype]

Commit c04fc586c (mm: show node to memory section relationship with
symlinks in sysfs) created symlinks from nodes to memory sections, e.g.
/sys/devices/system/node/node1/memory135 -> ../../memory/memory135
If you're examining the memory section though and are wondering what node
it might belong to, you can find it by grovelling around in sysfs, but
it's a little cumbersome.
Add a reverse symlink for each memory section that points back to the
node to which it belongs.

Version 3 of this patch is updated with documentation added to
Documentation/ABI. There are no changes to any of the C code from v2
of the patch.
In order to support kernel DLPAR of CPU resources we need to provide an
interface to add (probe) and remove (release) the resource from the system.
This patch Creates new generic probe and release sysfs files to facilitate
cpu probe/release. The probe/release interface provides for allowing each
arch to supply their own routines for implementing the backend of adding
and removing cpus to/from the system.
This also creates the powerpc specific stubs to handle the arch callouts
from writes to the sysfs files.
The creation and use of these files is regulated by the
CONFIG_ARCH_CPU_PROBE_RELEASE option so that only architectures that need the
capability will have the files created.
