All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

Stop using kobject_register for this static kobject, as it's overkill.
This way is much simpler.

There is no firmware "subsystem" it's just a directory in /sys that
other portions of the kernel want to hook into. So make it a kobject
not a kset to help alivate anyone who tries to do some odd kset-like
things with this.

We don't need a kset here, a simple kobject will do just fine, so
dynamically create the kobject and use it.

We don't need a "default" ktype for a kset. We should set this
explicitly every time for each kset. This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.
This patch is based on a lot of help from Kay Sievers.

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

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".

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.

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 linux-acpi@vger.kernel.org
ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org
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 linux-acpi@vger.kernel.org
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

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 and APM used "pm_active" to guarantee that
they would not be simultaneously active.
But pm_active was recently moved under CONFIG_PM_LEGACY,
so that without CONFIG_PM_LEGACY, pm_active became a NOP --
allowing ACPI and APM to both be simultaneously enabled.
This caused unpredictable results, including boot hangs.
Further, the code under CONFIG_PM_LEGACY is scheduled
for removal.
So replace pm_active with pm_flags.
pm_flags depends only on CONFIG_PM,
which is present for both CONFIG_APM and CONFIG_ACPI.
