ACPI patches for 2.6.24-rc8

reviewerPATCH 1/1 ACPI patches for 2.6.24-rc8
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
This fixes a couple of 2.6.24 regressions, and also installs the latest DMI blacklist. While the DMI blacklist is a lot of text, it is almost entirely about avoiding dmesg spam to make the release more supportable. Indeed, I plan to submit the DMI update to 2.6.23.stable.
This will update the files shown below.
thanks!
-Len

ACPI: EC: "DEBUG" needs to be defined earlier
The "DEBUG" symbol needs to be defined before #including <linux/kernel.h> to get the pr_debug() working.

Author: Márton Németh <[email protected]> Date: Wed Jan 23 22:33:06 2008 -0500
ACPI: EC: add leading zeros to debug messages
Add leading zeros to pr_debug() calls. For example if x=0x0a, the format "0x%2x" will result the string "0x a", the format "0x%2.2x" will result "0x0a".

ACPI: DMI blacklist to reduce console warnings on OSI(Linux) systems.
This DMI blacklist reduces the console messages on systems which have a BIOS that invokes OSI(Linux).
As the DMI blacklist already knows about these systems, the request for DMI info itself is disabled.
Further, if OSI(Linux) has already been determined to have no beneift, we disable the console message requesting acpi_osi=Linux test results.

ACPI: make _OSI(Linux) console messages smarter
If BIOS invokes _OSI(Linux), the kernel response depends on what the ACPI DMI list knows about the system, and that is reflectd in dmesg:
1) System unknown to DMI:
ACPI: BIOS _OSI(Linux) query ignored
ACPI: DMI System Vendor: LENOVO
ACPI: DMI Product Name: 7661W1P
ACPI: DMI Product Version: ThinkPad T61
ACPI: DMI Board Name: 7661W1P
ACPI: DMI BIOS Vendor: LENOVO
ACPI: DMI BIOS Date: 10/18/2007
ACPI: Please send DMI info above to [email protected]
ACPI: If "acpi_osi=Linux" works better, please notify [email protected]
2) System known to DMI, but effect of OSI(Linux) unknown:
ACPI: DMI detected: Lenovo ThinkPad T61
...
ACPI: BIOS _OSI(Linux) query ignored via DMI
ACPI: If "acpi_osi=Linux" works better, please notify [email protected]
3) System known to DMI, which disables _OSI(Linux):
ACPI: DMI detected: Lenovo ThinkPad T61
...
ACPI: BIOS _OSI(Linux) query ignored via DMI
4) System known to DMI, which enable _OSI(Linux):
ACPI: DMI detected: Lenovo ThinkPad T61
ACPI: Added _OSI(Linux)
...
ACPI: BIOS _OSI(Linux) query honored via DMI
cmdline overrides take precidence over the built-in default and the DMI prescribed default. cmdline "acpi_osi=Linux" results in:
ACPI: BIOS _OSI(Linux) query honored via cmdline
commit 7ce95ce5c6dbbc3f70933f04537860ffd9dbe17e

ACPI: Delete Intel Customer Reference Board (CRB) from OSI(Linux) DMI list
Linux does not want BIOS writers to invoke _OSI(Linux) - for in the field it causes more Windows incompatibility problems than it solves.
So when it is seen in the BIOS for an Intel Customer Reference Board, Linux should ignore its effect by default, and should complain loudly. Otherwise, the reference BIOS will go unfixed, and the bad BIOS will spread to the field.
Users of this board can get the old behavior with "acpi_osi=Linux"
As this was the only entry, delete acpi_osl_dmi_table[].

ACPI: create acpi_dmi_dump()
A utility routine to print common entries used for ACPI-related DMI blacklist entries.

DMI: create dmi_get_slot()
This simply allows other sub-systems (such as ACPI) to access and print out slots in static dmi_ident[].
