As of version 2.0, ACPI can return 64-bit integers. The current

Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.

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.

CONFIG_PNP_DEBUG is no longer used to turn on dev_dbg() in PNP,
since we have pnp_dbg() which can be enabled at boot-time, so
this patch removes the config option.
Note that pnp_dock_event() checks "#ifdef DEBUG". But there's
never been a clear path for enabling that via configgery. It
happened that CONFIG_PNP_DEBUG enabled it after 1bd17e63a0,
but that was accidental and only in 2.6.26.

Use scnprintf() to build up a buffer of PNP IDs to print. This
makes the printk atomic and helps get rid of an #ifdef.
Also remove an "#ifdef DEBUG" from some debug functions. The
functions only produce debug output, so it's OK to run the
function and just have the output be dropped at the end.
