Lv Zheng 45c9f78b25 ACPICA: Add __init for ACPICA initializers/finalizers.
This patch adds __init to the ACPICA documented initializers:
  acpi_initialize_tables()
  acpi_initialize_subsystem()
  acpi_load_tables()
  acpi_enable_subsystem()
  acpi_initialize_objects()
and to acpi_reallocate_root_table(), acpi_find_root_pointer() which
are also meant to be called only during initialization.

This patch adds __init to the ACPICA documented finalizer:
  acpi_terminate()
as this finalizer is only called in __init function now.

This change helps to reduce source code differences between
ACPICA upstream and Linux.

It is reported by kernel build test systems that all ACPICA source
files in the kernel tree have incorrect label indentation.  This
patch changes default indent option used in the release process to
fix this bug.  Lv Zheng.

Lv Zheng 9c0d793945 ACPICA: Cleanup coding style to reduce differences between Linux and ACPICA.
This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.

This patch does not affect the generation of the Linux binary.
This patch decreases 314 lines of 20121018 divergence.diff.

ACPICA core uses ()'s on return statements. This is a known and committed
differences from Linux standard coding style.

This patch cleans up the Linux side ACPICA code to use this codying style
in order to reduce the source code differences between Linux and ACPICA.

Bob Moore f7b004a17c ACPICA: Add acpi_os_physical_table_override interface
This interface allows the host to override a table via a
physical address, instead of the logical address required by
acpi_os_table_override. This simplifies the host implementation.
Initial implementation by Thomas Renninger. ACPICA implementation
creates a single function for table overrides that attempts both
a logical and a physical override.

Lin Ming aa2110cb1a ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT
Some BIOS on Toshiba machines corrupt the DSDT, so add a new
boot option acpi=copy_dsdt to workaround it.
Add warning message to ask users to use this option if corrupt DSDT detected.

Also build a DMI blacklist to check it and automatically copy DSDT.

Myron Stowe 386e4a8358 ACPICA: Fix table entry truncation calculation
During early boot, ACPI RSDT/XSDT table entries are gathered into the
'initial_tables[]' array.  This array is currently statically defined (see
./drivers/acpi/tables.c).  When there are more table entries than can be
held in the 'initial_tables[]' array, the message "Truncating N table
entries!" is output.  As currently implemented, this message will always
erroneously calculate N as 0.

This patch fixes the calculation that determines how many table entries
will be missing (truncated).

This modification may be used under either the GPL or the BSD-style
license used for Intel ACPI CA code.
