ACPI: acpi_os_allocate() fixes
ACPI: SBS: fix initialization, sem2mutex
ACPI: add 'const' to several ACPI file_operations
ACPI: delete some defaults from ACPI Kconfig
ACPI: "Device `[%s]' is not power manageable" make message debug only
ACPI: ACPI_DOCK Kconfig
Revert "Revert "ACPI: dock driver""
ACPI: acpi_os_get_thread_id() returns current
ACPI: ACPICA 20060707
Daniel Ritz <daniel.ritz-ml@swissonline.ch> says:
The acpi driver suspend/resume patches that went in recently caused a regression
on my box (toshiba tecra 8000 laptop): after resume from swsusp the fan turns on
keeping blowing cold air out of my notebook. before the patches, the fan was off
and would only make noise when required. it's the same thing described in
bugzilla.kernel.org #5000. the acpi suspend/resume patches or at least parts of
them originate in this bug. now the last patch in the report (attach id 8438)
actually fixes the problem - for me and the reporter. this is a trimmed down
version of that patch.

Replace acpi_in_resume with a more general hack
to check irqs_disabled() on any kmalloc() from ACPI.
While setting (system_state != SYSTEM_RUNNING) on resume
seemed more general, Andrew Morton preferred this approach.

Make acpi_os_allocate() into an inline function to
allow /proc/slab_allocators to work.
Delete some memset() that could fault on allocation failure.

cm_sbs_sem is being downed (via acpi_ac_init->acpi_lock_ac_dir) before it is
initialised, with grave results.
- Make it a mutex
- Initialise it
- Make it static
- Clean other stuff up.
Thanks to Paul Drynoff <pauldrynoff@gmail.com> for reporting and testing.

HOTPLUG_PCI_ACPI depends on ACPI_DOCK
ACPI_IBM_DOCK depends on ACPI_DOCK=n
ACPI_DOCK is EXPERIMENTAL, though that doesn't seem to mean much

Linux mutexes and the debug code that that reference
acpi_os_get_thread_id() are happy with 0.
But the AML mutexes in exmutex.c expect a unique non-zero
number for each thread - as they track this thread_id
to permit the mutex re-entrancy defined by the ACPI spec.

Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to
support C compilers that do not allow the initialization
of address pointers within packed structures - even though
the hardware itself may support misaligned transfers. Some
of the debug data structures are packed by default to
minimize size.
Added an error message for the case where
acpi_os_get_thread_id() returns zero. A non-zero value is
required by the core ACPICA code to ensure the proper
operation of AML mutexes and recursive control methods.
The DSDT is now the only ACPI table that determines whether
the AML interpreter is in 32-bit or 64-bit mode. Not really
a functional change, but the hooks for per-table 32/64
switching have been removed from the code. A clarification
to the ACPI specification is forthcoming in ACPI 3.0B.
Fixed a possible leak of an Owner ID in the error
path of tbinstal.c acpi_tb_init_table_descriptor() and
migrated all table OwnerID deletion to a single place in
acpi_tb_uninstall_table() to correct possible leaks when using
the acpi_tb_delete_tables_by_type() interface (with assistance
from Lance Ortiz.)
Fixed a problem with Serialized control methods where the
semaphore associated with the method could be over-signaled
after multiple method invocations.
Fixed two issues with the locking of the internal
namespace data structure. Both the Unload() operator and
acpi_unload_table() interface now lock the namespace during
the namespace deletion associated with the table unload
(with assistance from Linn Crosetto.)
Fixed problem reports (Valery Podrezov) integrated: -
Eliminate unnecessary memory allocation for CreateXxxxField
http://bugzilla.kernel.org/show_bug.cgi?id=5426
Fixed problem reports (Fiodor Suietov) integrated: -

- On Address Space handler deletion, needless deactivation
call (BZ 374) - AcpiRemoveAddressSpaceHandler: validate

This reverts commit a5e1b94008.
Adrian Bunk points out that it has build errors, and apparently no
maintenance. Throw it out.
