acpi_unload_table_id() is always returning an error status.
Also, once the matching table is found, don't bother looking
for another match.

Support for 16-bit ACPICA has been completely removed since it is
no longer necessary and it clutters the code. All 16-bit macros,
types, and conditional compiles have been removed, cleaning up
and simplifying the code across the entire subsystem.
DOS support is no longer needed since the Linux firmware kit
is now available.

The Table Manager component has been completely
redesigned and reimplemented. The new design is much
simpler, and reduces the overall code and data size of
the kernel-resident ACPICA by approximately 5%. Also,
it is now possible to obtain the ACPI tables very early
during kernel initialization, even before dynamic memory
management is initialized.

Make acpi_load_table() available for use by removing it from the #ifdef
ACPI_FUTURE_USAGE.
Also add a new routine used to unload an ACPI table of a given type and "id" -
acpi_unload_table_id(). The implementation of this new routine was almost a
direct copy of existing routine acpi_unload_table() - only difference being
that it only removes a specific table id instead of ALL tables of a given
type. The SN hotplug driver (sgi_hotplug.c) now uses both of these interfaces
to dynamically load and unload SSDT ACPI tables.
Also, a few other ACPI routines now used by the SN hotplug driver are exported
(since the driver can be a loadable module):
acpi_ns_map_handle_to_node
acpi_ns_convert_entry_to_handle
acpi_ns_get_next_node

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.)

Converted the locking mutex used for the ACPI hardware
to a spinlock. This change should eliminate all problems
caused by attempting to acquire a semaphore at interrupt
level, and it means that all ACPICA external interfaces
that directly access the ACPI hardware can be safely
called from interrupt level.
Fixed a regression introduced in 20060526 where the ACPI
device initialization could be prematurely aborted with
an AE_NOT_FOUND if a device did not have an optional
_INI method.
Fixed an IndexField issue where a write to the Data
Register should be limited in size to the AccessSize
(width) of the IndexField itself. (BZ 433, Fiodor Suietov)
