Merge Upstream's stable 3.0.21 branch into msm-3.0
This consists 814 commits and some merge conflicts.
The merge conflicts are because of some local changes to

The debugging functions in SPS driver are enhanced as follows:
1> Change some logging output from pr_info() to pr_debug() to reduce
log amount.
2> Formalize the log content since some logs did not have the keyword
which shows they are from SPS driver. This modification can help
people find the error or other information from SPS driver more
conveniently.
3> SPS driver did not output error messages in some places where an
error is captured. Add error message output for these places.
4> SPS driver is used by some peripherals (such as SDCC) which have
high throughput. When DEBUG level logging is enabled, the log
output is tremendous and sometimes even hinders the analysis of
the log, although some log messages are very helpful to the
debugging of particular issues. Thus, add fine-grained DEBUG level
log output control via debugfs.
5> Add the options via debugfs which dump the content of selected BAM
registers. This can help analyze the BAM-related issues without
additional software tools.

commit bee460be8c upstream.
The min_brightness value of the sabi_config is incorrectly used in brightness
calculations. For the config where min_brightness = 1 and max_brightness = 8,
the user visible range should be 0 to 7 with hardware being set in the range
of 1 to 8. What is actually happening is that the user visible range is 0 to
8 with hardware being set in the range of -1 to 7.
This patch fixes the above issue as well as a miscalculation that would occur
in the case of min_brightness > 1.

Handle events 0x4010 and 0x4011 so that we do not pester users about them.
These events report when the thinkpad is docked/undocked to a native
hotplug dock (i.e. one that does not need ACPI handling, nor is represented
in the ACPI device tree). Such docks are based on USB 2.0/3.0, and also
work as port replicators.
We really want a proper dock class to report these, or at least new input
EV_SW events. Since it is not clear which one to use yet, keep reporting
them as vendor-specific ThinkPad events.
WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the
vendor-specific events will be REMOVED as soon as generic events are made
available (duplicate events are a big problem), with an appropriate update
to the thinkpad-acpi sysfs/event ABI versioning. Userspace is already
prepared to provide easy backwards compatibility for such changes when
convenient to the distro (see acpi-fakekey).
* Event 0x4010: docking to hotplug dock/port replicator
* Event 0x4011: undocking from hotplug dock/port replicator
Typical usecase would be to trigger display reconfiguration.
Reports mention T410, T510, and series 3 docks/port replicators. Special
thanks to Robert de Rooy for his extensive report and analysis of the
situation.

Handle some user interface events from the newer Lenovo models. We are likely
to do something smart with these events in the future, for now, hide the ones
we are already certain about from the user and userspace both.
* Events 0x6000 and 0x6005 are key-related. 0x6005 is not properly identified
yet. Ignore these events, and do not report them.
* Event 0x6040 has not been properly identified yet, and we don't know if it
is important (looks like it isn't, but still...). Keep reporting it.
* Change the message the driver outputs on unknown 0x6xxx events, as all
recent events are not related to thermal alarms. Degrade log level from
ALERT to WARNING.
Thanks to all users who reported these events or asked about them in a number
of mailing lists. Your help is highly appreciated, even if I did took a lot of
time to act on them. For that I apologise.
I will list those that identified the reasons for the events as "reported-by",
and I apologise in advance if I leave anyone out: it was not done on purpose, I
made the mistake of not properly tagging all event report emails separately,
and might have missed some.

acer-wmi is indiscriminately using the device state from hotkey
events to update the various rfkill states. On the Aspire 1830 this
can result in a soft block on the wlan when the touchpad hotkey is
pressed, as it is reporting a non-zero device state that does not
reflect the wireless status. To fix this, only update rfkill states
when a wlan or bluetooth hotkey is pressed.
