ACPI: Reject below-freezing temperatures as invalid critical temperatures
My laptop thinks that it's a good idea to give -73C as the critical
CPU temperature.... which isn't the best thing since it causes a shutdown
right at bootup.
Temperatures below freezing are clearly invalid critical thresholds
so just reject these as such.

ACPICA: Ignore ACPI table signature for Load() operator
Only "SSDT" is acceptable to the ACPI spec, but tables are
seen with OEMx and null sigs. Therefore, signature validation
is worthless. Apparently MS ACPI accepts such signatures, ACPICA

bay: exit if notify handler cannot be installed
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.

PNPACPI: use _CRS IRQ descriptor length for _SRS
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.
This is an extension of a patch by Tom Jaeger:

pnpacpi: fix shareable IRQ encode/decode
When we encode IRQ resources, we should use the "shareable" flag we got
from _PRS rather than guessing based on the IRQ trigger mode.

pnpacpi: fix IRQ flag decoding
When decoding IRQ trigger mode and polarity, it is not enough to mask by
IORESOURCE_BITS because there are now additional bits defined. For
example, if IORESOURCE_IRQ_SHAREABLE was set, we failed to set *triggering
and *polarity at all.
I can't point to a failure that this patch fixes, but
bugs in this area have caused problems when resuming after
suspend, for example:

ACPI 2.6.26-rc2: Add missing newline to DSDT/SSDT warning message
As of recently (probably 2.6.26-rc1) I've been getting the following mangling

thinkpad-acpi: fix LED handling on older ThinkPads
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".
Issue reported by Karol Lewandowski <lmctlx@...il.com> (he's an lucky guy
and got an OOPS instead of silent corruption :-) ).
Root cause of the OOPS identified by Adrian Bunk <bunk@...nel.org>.

cpuidle acpi driver: fix oops on AC<->DC
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.
