This patch tries to identify which devices are able to accept
reset-resume handling, by checking that there is at least one
interface driver bound and that all of the drivers have a reset_resume
method defined. If these conditions don't hold then during resume
processing, the device is logicall disconnected.
This is only a temporary fix. Later on we will explicitly unbind
drivers that can't handle reset-resumes.

If acpi_install_notify_handler() for a bay device fails, the bay driver is
superfluous. Most likely, another driver (like libata) is already caring
about this device anyway. Furthermore,
register_hotplug_dock_device(acpi_handle) from the dock driver must not be
called twice with the same handler. This would result in an endless loop
consuming 100% of CPU. So clean up and exit.

When configuring the resources of an ACPI device, we first evaluate _CRS
to get a template of resource descriptors, then fill in the specific
resource values we want, and finally evaluate _SRS to actually configure
the device.
Some resources have optional fields, so the size of encoded descriptors
varies depending on the specific values. For example, IRQ descriptors can
be either two or three bytes long. The third byte contains triggering
information and can be omitted if the IRQ is edge-triggered and active
high.
The BIOS often assumes that IRQ descriptors in the _SRS buffer use the
same format as those in the _CRS buffer, so this patch enforces that
constraint.
The "Start Dependent Function" descriptor also has an optional byte, but
we don't currently encode those descriptors, so I didn't do anything for
those.
I have tested this patch on a Toshiba Portege 4000. Without the patch,
parport_pc claims the parallel port only if I use "pnpacpi=off". This
patch makes it work with PNPACPI.

The less tested codepaths for LED handling, used on ThinkPads 570, 600e/x,
770e, 770x, A21e, A2xm/p, T20-22, X20 and maybe a few others, would write
data to kernel memory it had no business touching, for leds number 3 and
above. If one is lucky, that illegal write would cause an OOPS, but
chances are it would silently corrupt a byte.
The problem was introduced in commit af116101, "ACPI: thinkpad-acpi: add
sysfs led class support to thinkpad leds (v3.2)".
Fix the bug by refactoring the entire code to be far more obvious on what
it wants to do. Also do some defensive "constification".

cpuidle and acpi driver interaction bug with the way cpuidle_register_driver()
is called. Due to this bug, there will be oops on
AC<->DC on some systems, where they support C-states in one DC and not in AC.
The current code does
ON BOOT:
Look at CST and other C-state info to see whether more than C1 is
supported. If it is, then acpi processor_idle does a
cpuidle_register_driver() call, which internally enables the device.
ON CST change notification (AC<->DC) and on suspend-resume:
acpi driver temporarily disables device, updates the device with
any new C-states, and reenables the device.
The problem is is on boot, there are no C2, C3 states supported and we skip
the register. Later on AC<->DC, we may get a CST notification and we try
to reevaluate CST and enabled the device, without actually registering it.
This causes breakage as we try to create /sys fs sub directory, without the
parent directory which is created at register time.
Thanks to Sanjeev for reporting the problem here.
