Freezeable workqueue makes sure that adapter work items (device insertions
and removals) would be handled after the system is fully resumed. Previously
this was achieved by explicit freezing of the kthread.

Get the IO resources list in sony-laptop in the same order as listed
in sonypi and make sonypi check if one of those is already busy.
The sonypi check can be disabled by a module parameter in case the user
thinks we are plainly wrong (check_ioport=0).

The dock sub-driver has split-personality (two subdrivers), and it was
doing some unoptimal things on init because of that. Fix it so that the
second half of it will only init when necessary, and only if the first half
initialized sucessfully in the first place.

Currently, all fan control operations return ENXIO if unsupported
operations are requested, but return EINVAL if invalid fan modes are
requested on a given ThinkPad.
This is not strictly correct for sysfs, so map ENXIO to EINVAL in the sysfs
attribute store handlers, as we do benefit from the ENXIO in other parts of
the driver code.

Len Brown considers that an active by default fan control interface in
laptops may be too close to giving users enough rope. There is a good
chance he is quite correct on this, especially if someone decides to use
that interface in applets and users are not aware of its risks.
This patch adds a master switch to thinkpad-acpi that enables or disables
the entire fan-control feature as a module parameter: "fan_control". It
defaults to disabled. Set it to non-zero to enable fan control.
Also, the patch removes the expermiental status from fan control, since it
is stable enough to not be called experimental, and the master switch makes
it safe enough to do so.
