8efe444038 power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL
The CAPACITY_LEVEL stuff defines various levels of charge; however, what
is the difference between them?  What differentiates between HIGH and NORMAL,
LOW and CRITICAL, etc?

As it appears that these are fairly arbitrary, we end up making such policy
decisions in the kernel (or in hardware).  This is the sort of decision that
should be made in userspace, not in the kernel.

If the hardware does not support _CAPACITY and it cannot be easily calculated,
then perhaps the driver should register a custom CAPACITY_LEVEL attribute;
however, userspace should not become accustomed to looking for such a thing,
and we should certainly not encourage drivers to provide CAPACITY_LEVEL
stubs.

The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL.  The
OLPC battery driver is the only driver making use of this, so it's
removed from there as well.

60417f5976 ACPI suspend: Call _PTS before suspending devices
The ACPI 1.0 specification wants us to put devices into low power
states after executing the _PTS global control method, while ACPI
2.0 and later want us to do that in the reverse order.  The current
suspend code follows ACPI 2.0 in that respect which causes some
ACPI 1.0x systems to hang during suspend (ref.
http://bugzilla.kernel.org/show_bug.cgi?id=9528).

Make the suspend code execute _PTS before putting devices into low
power states (ie. in accordance with ACPI 1.0x) and provide a command
line option to override the default if need be.

Modify the hibernation userland interface by adding two new ioctls to it,
SNAPSHOT_PLATFORM_SUPPORT and SNAPSHOT_POWER_OFF, that can be used,
respectively, to switch the hibernation platform support on/off and to make the
kernel transition the system to the hibernation state (eg. ACPI S4) using the
platform (eg. ACPI) driver.

These ioctls are intended to replace the misdesigned SNAPSHOT_PMOPS ioctl,
which from now is regarded as obsolete and will be removed in the future.

782e70c6fc USB: mark USB drivers as being GPL only
Over two years ago, the Linux USB developers stated that they believed
there was no way to create a USB kernel driver that was not under the
GPL.  This patch moves the USB apis to enforce that decision.

There are no known closed source USB drivers in the wild, so this patch
should cause no problems.

29e75252da [IPV4] route cache: Introduce rt_genid for smooth cache invalidation
Current ip route cache implementation is not suited to large caches.

We can consume a lot of CPU when cache must be invalidated, since we
currently need to evict all cache entries, and this eviction is
sometimes asynchronous. min_delay & max_delay can somewhat control this
asynchronism behavior, but whole thing is a kludge, regularly triggering
infamous soft lockup messages. When entries are still in use, this also
consumes a lot of ram, filling dst_garbage.list.

A better scheme is to use a generation identifier on each entry,
so that cache invalidation can be performed by changing the table
identifier, without having to scan all entries.
No more delayed flushing, no more stalling when secret_interval expires.

Invalidated entries will then be freed at GC time (controled by
ip_rt_gc_timeout or stress), or when an invalidated entry is found
in a chain when an insert is done.
Thus we keep a normal equilibrium.

This patch :
- renames rt_hash_rnd to rt_genid (and makes it an atomic_t)
- Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit)
- Checks entry->rt_genid at appropriate places :

The xfer_align sw_params parameter has never been used in a sane manner,
and no one understands what this does exactly.  The current
implementation looks also buggy because it allows write of shorter size
than xfer_align.  So, if you do partial writes, the write isn't actually
aligned at all.
Removing this parameter will make some pcm_lib_* code more readable
(and less buggy).

86c53bd26b [ALSA] hda-codec - Add test model for ALC268
This implements a test model for the ALC268.  It depends on the feature
added by alc260-test-eapd-0.2.diff.  This patch also adds a mention of
the ALC260 test model to ALSA-Configuration.txt since this seems to have
been missed.

5aba4f8ec7 [ALSA] hda-intel - Support multiple devices
It turned out that there can be multiple HD-audio devices on a single
machine (e.g. on-board audio and HDMI on graphic cards), so we need to
support multiple devices with snd-hda-intel driver.

The attached patch adds initial support of the Mitac 8252D
(http://www.mitac-mtc.com.tw/English/products/8252Dspec.htm).
Working:
 - Front speakers (volume + mute)
 - Center/LFE speakers (volume + mute)
 - HP out (with Front Volume)
 - HP individual mute switch
 - HP Jack sense
 - Front Mic and its volume
Not tested:
 - external mic and its volume
Not working while now:

109c53f840 [ALSA] sound/isa: kill pnp_resource_change
This removes the pnp_resource_change use from the ALSA ISAPnP drivers. In
2.4 these were useful in providing an easy path to setting the resources,
but in 2.6 they retain function as a layering violation only.
This makes for a nice cleanup (-550 lines) of ALSA but moreover, ALSA is the
only remaining user of pnp_init_resource_table(), pnp_resource_change() and
pnp_manual_config_dev() (and, in fact, of 'struct pnp_resource_table') in
the tree outide of drivers/pnp itself meaning it makes for more cleanup
potential inside the PnP layer.
Thomas Renninger acked their removal from that side, you did from the ALSA
side (CC list just copied from that thread).
Against current alsa-kernel HG. Many more potential cleanups in there, but
this _only_ removes the pnp_resource_change code. Compile tested against
current alsa-kernel HG and compile- and use-tested against 2.6.23.x (few
offsets).

304cd07f92 [ALSA] Introduce slots option to snd module
Introduced the global 'slots' option to snd module.  This option provides
an alternative way to handle the order of multiple sound card instances.
It's an easier approach to avoid conflict with hotplug devices, and can
be used together with the existing 'order' option of each card driver.
