This reverts commit a3d77411e8,
as it causes a mess in the wireless rfkill status on some models.
It is probably a bad idea to toggle the rfkill for all dell models
without the respect to the claim that it is hardware-controlled.

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.

The distinction between scic_sds_ scic_ and sci_ are no longer relevant
so just unify the prefixes on sci_. The distinction between isci_ and
sci_ is historically significant, and useful for comparing the old
'core' to the current Linux driver. 'sci_' represents the former core as
well as the routines that are closer to the hardware and protocol than
their 'isci_' brethren. sci == sas controller interface.

The tci_pool tracks our outstanding command slots which are also the 'index'
portion of our tags. Grabbing the tag early in ->lldd_execute_task let's us
drop the isci_host_can_queue() and ->was_tag_assigned_by_user infrastructure.
->was_tag_assigned_by_user required the task context to be duplicated in
request-local buffer. With the tci established early we can build the
task_context directly into its final location and skip a memcpy.
With the task context buffer at a known address at request construction we
have the opportunity/obligation to also fix sgl handling. This rework feels
like it belongs in another patch but the sgl handling and task_context are too
intertwined.
1/ fix the 'ab' pair embedded in the task context to point to the 'cd' pair in
the task context (previously we were prematurely linking to the staging
buffer).
2/ fix the broken iteration of pio sgls that assumes all sgls are relative to
the request, and does a dangerous looking reverse lookup of physical
address to virtual address.
