commit 6158d3a2323835546c7cf83a170316fa77b726e0 upstream.

At least the Vaio VGN-Z540N doesn't have this method, so let's not fail
to suspend just because it doesn't exist.

Creates a name file in the sysfs directory, that
is needed for the libsensors library to work.
Also rename fan1_pwm to pwm1 and scale its value as needed.

This fixes bug #11520:

If you are on ia64 and you modprobe xpc then modprobe -r xpc, you
immediately get a panic.  xpc depends on xp which depends on gru for a
symbol.  That symbol is only used when we are running on UV hardware.

Currently, the GRU driver detects we are not on UV hardware and does no
initializing.  It does not do the same check when unloading.  As a result,
the gru driver attempts to tear down stuff that was not setup.

This is a simple two-line workaround to get us through this release.  Once
2.6.28 is opened, we need to rework the symbols that xp is depending on
from gru so the gru driver can properly fail to load when hardware is not
available.

* 'release-2.6.27' of git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-acpi-2.6:
  acer-wmi: remove debugfs entries upon unloading
  ACPI: Avoid bogus timeout about SMbus check
  fujitsu-laptop: fix regression for P8010 in 2.6.27-rc
  ACPI: Make Len Brown the ACPI maintainer again
  ACPI: thinkpad-acpi: wan radio control is not experimental
  PNPACPI: ignore the producer/consumer bit for extended IRQ descriptors
  acpi: add checking for NULL early param
  ACPI: Fix typo in "Disable MWAIT via DMI on broken Compal board"
  ACPI: Fix now signed module parameter.
  ACPI: Change package length error to warning
  ACPI: Fix now signed module parameter.

The exit function neglects to remove debugfs entries, leading to a BUG
on reload.

The following patch (based on a patch from Stephen Gildea) fixes a
regression with the LCD brightness keys on Fujitsu P8010 laptops which was
observed with the 2.6.27-rc series (basically they stopped working due to
changes within the fujitsu-laptop and video modules).  Please apply to
2.6.27-rc and acpi git.

A more complete solution for this laptop will be included in an upcoming
patch, hopefully for 2.6.28.  In the meantime this restores most
functionality for P8010 users.

It turns out that event 0x4 merely indcates that a hotkey has been
pressed, not which one.  A further query is required in order to determine
the actual keypress.  The following patch adds support for that along with
the known keycodes.

hp-wmi currently changes the RFKill state by altering the struct members
rather than using the dedicated interface, meaning that update events
won't be pushed to userspace.  This patch fixes that, along with fixing
the declared type of the WWAN kill switch.  It also ensures that rfkill
interfaces are only registered for hardware that exists.
