v2->v1:
.improve debug info as suggedted by Bjorn,Kenji
.API is using uuid string as suggested by Alexey
Add an API to execute _OSC. A lot of devices can have this method, so add a
generic API.

linux/acpi.h is the top level header for interfacing
with the ACPI sub-system, so acpi_disabled should be
up there instead of down in asm/acpi.h -- particularly
since asm/acpi.h doesn't exist for all architectures.
Same story for acpi_table_parse(), which is a top-level
API to Linux/ACPI.
This is necessary for building some code that
used to always depend on CONFIG_ACPI=y, but will soon
also need to build with CONFIG_ACPI=n.

Move
arch/x86/kernel/acpi/boot.c: acpi_parse_mcfg()
to
arch/x86/pci/mmconfig-shared.c: pci_parse_mcfg()
where it is used, and make it static.
Move associated globals and helper routine with it.
No functional change.
This code move is in preparation for SFI support,
which will allow the PCI code to find the MCFG table
on systems which do not support ACPI.

All logical processors with APIC ID values of 255 and greater will have their
APIC reported through Processor X2APIC structure (type-9 entry type) and all
logical processors with APIC ID less than 255 will have their APIC reported
through legacy Processor Local APIC (type-0 entry type) only. This is the
same case even for NMI structure reporting.
The Processor X2APIC Affinity structure provides the association between the
X2APIC ID of a logical processor and the proximity domain to which the logical
processor belongs.
For OSPM, Procssor IDs outside the 0-254 range are to be declared as Device()
objects in the ACPI namespace.

Fix trivial append-only conflict in Documentation/feature-removal-schedule.txt
- Rename pci_osc_control_set() to acpi_pci_osc_control_set() according
to the other API names in drivers/acpi/pci_root.c.
- Move _OSC related definitions to include/linux/acpi.h because _OSC
related API is implemented in drivers/acpi/pci_root.c now.

to prevent wrongly overwriting fixmap that still want to use.
ACPI used to rely on low mappings being all linearly mapped and
grew a habit: it never really unmapped certain kinds of tables
after use.
This can cause problems - for example the hypothetical case
when some spurious access still references it.
v2: remove prev_map and prev_size in __apci_map_table
v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to
early_acpi_os_unmap_memory
v4: fix typo in one acpi_get_table_with_size calling

If an ACPI graphics device supports backlight brightness functions (cmp. with
latest ACPI spec Appendix B), let the ACPI video driver control backlight and
switch backlight control off in vendor specific ACPI drivers (asus_acpi,
thinkpad_acpi, eeepc, fujitsu_laptop, msi_laptop, sony_laptop, acer-wmi).
Currently it is possible to load above drivers and let both poke on the
brightness HW registers, the video and vendor specific ACPI drivers -> bad.
This patch provides the basic support to check for BIOS capabilities before
driver loading time. Driver specific modifications are in separate follow up
patches.
