Validates predefined ACPI objects that appear in the namespace,
at the time they are evaluated. The argument count and the type of
the returned object are validated. The purpose of this validation
is to detect problems with the BIOS-exposed predefined ACPI objects
before the results are returned to the ACPI-related drivers.

Maybe the incorrect power state is returned on the bogus bios, which
is different with the real power state. For example: the bios returns D0
state and the real power state is D3. OS expects to set the device to D0
state. In such case if OS uses the power state returned by the BIOS and
checks the device power state very strictly in power transition, the device
can't be transited to the correct power state.
So the boot option of "acpi.power_nocheck=1" is added to avoid checking
the device power in the course of device power transition.

when there is no ECDT table and no _INI object for EC device, it will be
enabled before scanning ACPI device. But it is too late after the following
the commit is merged.

>x86: validate against acpi motherboard resources
After the above commit is merged, OS will check whether MCFG area is
reserved in ACPI motherboard resources by calling the function of
acpi_get_devices when there exists MCFG table. In the acpi_get_devices the _STA
object will be evaluated to check the status of the ACPI device. On some broken
BIOS the MYEC object of EC device is initialized as one, which indicates that
EC operation region is already accessible before enabling EC device.So on these
broken BIOS the EC operation region will be accessed in course of evaluating
the _STA object before enabling EC device, which causes that OS will print the
following warning messages:
>ACPI Error (evregion-0315): No handler for Region [EC__] (ffff88007f8145e8)
[EmbeddedControl] [20080609]
>ACPI Error (exfldio-0290): Region EmbeddedControl(3) has no handler [20080321]
>ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG.
EC__.BAT1._STA] (Node ffff81013fc17a00), AE_NOT_EXIST
>ACPI Error (uteval-0233): Method execution failed [\_SB_.PCI0.SBRG.EC__.BAT1.
_STA] (Node ffff81013fc17a00), AE_NOT_EXIST
Although the above warning message is harmless, it looks confusing.
So it is necessary to enable EC device as early as possible.Maybe it is
appropriate to enable it immediately after ACPI full initialization.

The hotplug notification handler and drivers' notification handler all
run in one workqueue. Before hotplug removes an acpi device, the
device driver's notification handler is already be recorded to run just
after global notification handler. After hotplug notification handler
runs, acpica will notice a NULL notification handler and crash.
So now we run run hotplug in another workqueue and wait
for all acpi notication handlers finish.
