ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941

The fixed table indexes leave holes in the global table list:
 1. One hole can be seen when there is only 1 FACS provided by the BIOS.
 2. Tow holes can be seen when it is a reduced hardware platform.
The holes do not break OSPMs but have broken ACPI debugger "tables"
command.

Also the "fixed table indexes" mechanism may make the descriptors of the
standard tables installed earlier than DSDT to be overwritten by the
descriptors of the fixed tables. For example, FACP disappears from the
global table list after DSDT is installed.

This patch fixes all above issues by removing the "fixed table indexes"
mechanism which is too complicated to be maintained in a regression safe
manner. After removal, the table loader will determine the indexes of the
fixed tables. Lv Zheng.

ACPICA commit 6eb364d790dd103bd4990f808e0095a421c437cb

acpi_tb_store_table() implements a logic that is only correct to iasl. So it
won't be used by any other utilities except iasl. This function is
complained by the kernel users as an unused function. The best choice to
stop releasing it to the Linux kernel should be moving it to adisasm.c.

ACPI table manager can use both struct acpi_table_desc (direct referencing)
and table index (indirect referencing) as the descriptor to the table, so
acpi_tb_get_next_root_index() is extended to return both of them to allow
maximum usability from the callers. NOTE that indirect referencing is a
design result to meet the boot stage static allocation requirement for the
table descriptors.

This is a linuxized acpi_tb_store_table() removing result, there should be
no functional changes introduced to the Linux kernel by this patch except
the additonal kernel unused argument for acpi_tb_get_next_root_index()
(renamed to acpi_tb_get_next_root_index()). This argument is used in the
ACPICA upstream.

It is reported that Linux x86 kernel cannot map large tables. The following
large SSDT table on such platform fails to pass checksum verification and
cannot be installed:
 ACPI: SSDT 0x00000000B9638018 07A0C4 (v02 INTEL  S2600CP  00004000 INTL 20100331)

It sounds strange that in the 64-bit virtual memory address space, we
cannot map a single ACPI table to do checksum verification. The root cause
is:
 1. ACPICA doesn't split IO memory mapping and table mapping;
 2. Linux x86 OSL implements acpi_os_map_memory() using a size limited fix-map
    mechanism during early boot stage, which is more suitable for only IO
    mappings.

ACPICA originally only mapped table header for signature validation, and
this header mapping is required by OSL override mechanism. There was no
checksum verification because we could not map the whole table using this
OSL. While the following ACPICA commit enforces checksum verification by
mapping the whole table during Linux boot stage and it finally triggers
this issue on some platforms:
 Commit: 86dfc6f3
 Subject: ACPICA: Tables: Fix table checksums verification before installation.

Before doing further cleanups for the OSL table mapping and override
implementation, this patch introduces an option for such OSPMs to
temporarily discard the checksum verification feature. It then can be
re-enabled easily when the ACPICA and the underlying OSL is ready.

This patch also deletes a comment around the limitation of mappings because
it is not correct. The limitation is not how many times we can map in the
early stage, but the OSL mapping facility may not be suitable for mapping
the ACPI tables and thus may complain us the size limitation.

The acpi_tb_verify_table() is renamed to acpi_tb_verify_temp_table() due to the
work around added, it now only applies to the table descriptor that hasn't
been installed and cannot be used in other cases. Lv Zheng.

The original table handling code does not always verify checksums before
installing a table, this is because code to achieve this must be
implemented here and there in the redundant code blocks.

There are two stages during table initialization:
1. "INSTALLED" after acpi_tb_install_table() and acpi_tb_override_table(),
   struct acpi_table_desc.Pointer is ensured to be NULL.  This can be safely used
   during OSPM's early boot stage.
2. "VALIDATED" after acpi_tb_validate_table(), struct acpi_table_desc.Pointer is
   ensured to be not NULL.  This must not be used during OSPM's early boot
   stage.

This patch changes acpi_tb_add_table() into an early boot safe API to reduce
code redundancies by changing the table state that is returned by this
function from "VALIDATED" to "INSTALLED".  Then the table verification
code can be done in a single place.  Originally, the acpi_tb_add_table() can
only be used by dynamic table loadings that are executed after early boot
stage, it cannot be used by static table loadings that are executed in
early boot stage as:
1.  The address of the table is a virtual address either maintained by
    OSPMs who call acpi_load_table() or by ACPICA whenever "Load" or
    "LoadTable" opcodes are executed, while during early boot stage,
    physical address of the table should be used for table loading.
2.  The API will ensure the state of the loaded table to be "VALIDATED"
    while during early boot stage, tables maintained by root table list
    should be kept as "INSTALLED".

To achieve this:
1. Rename acpi_tb_install_table() to acpi_tb_install_fixed_table() as it only
   applies to DSDT/FACS installation.  Rename acpi_tb_add_table() to
   acpi_tb_install_non_fixed_table() as it will be applied to the installation
   of the rest kinds of tables.
2. Introduce acpi_tb_install_table(), acpi_tb_install_and_override_table to collect
   redudant code where their invocations actually have slight differences.
   1. acpi_tb_install_table() is used to fill an struct acpi_table_desc where the
      table length is known to the caller.
   2. acpi_tb_install_and_override_table() is used to perform necessary
      overriding before installation.
3. Change a parameter of acpi_tb_install_non_fixed_table() from struct acpi_table_desc
   to acpi_physical_address to allow it to be invoked by static table
   loadings.  Also cleanup acpi_ex_load_op() and acpi_load_table() to accomodate
   to the parameter change.
4. Invoke acpi_tb_install_non_fixed_table() for all table loadings other than
   DSDT/FACS in acpi_tb_parse_root_table() to improve code maintainability
   (logics are collected in the single function).  Also delete useless code
   from acpi_tb_parse_root_table().
5. Remove all acpi_tb_validate_table() from acpi_tb_install_non_fixed_table() and
   acpi_tb_install_fixed_table() so that the table descriptor is kept in the
   state of "INSTALLED" but not "VALIDATED" after returning from these
   functions.
6. Introduce temporary struct acpi_table_desc (new_table_desc/old_table_desc) into
   the functions to indicate a table descriptor that is not maintained by
   acpi_gbl_root_table_list. Introduce acpi_tb_acquire_temporal_table() and
   acpi_tb_release_temporal_table() to handle the use cases of such temporal
   tables.  They are only used for verified installation.
7. Introduce acpi_tb_verify_table() to validate table and verify table
   checksum, also remove table checksum verification from
   acpi_tb_validate_table(). Invoke acpi_tb_validate_table() in the functions
   that will convert a table into "LOADED" state or invoke it from
   acpi_get_table_XXX() APIs. Invoke acpi_tb_verify_table() on temporary
   struct acpi_table_desc(s) that are going to be "INSTALLED".
8. Change acpi_tb_override_table() logic so that a temporary struct acpi_table_desc
   will be overridden before installtion, this makes code simpler.

After applying the patch, tables are always installed after being
overridden and the table checksums are always verified before installation.

This patch is mainly a naming cleanup to clarify hidden logics, no
functional changes.

acpi_initialize_tables() is used by Linux to install table addresses for
early boot steps.  During this stage, table addresses are mapped by
early_ioremap() mechanism which is different from the runtime IO mappings.
Thus it is not safe for ACPICA to keep mapped pointers in struct acpi_table_desc
structure during this stage.

In order to support this in ACPICA, table states are divided into
1. "INSTALLED" (where struct acpi_table_desc.Pointer is always NULL) and
2. "VALIDATED" (where struct acpi_table_desc.Pointer is always not NULL).
During acpi_initialize_tables(), table state are ensured to be "INSTALLED"
but not "VALIDATED".  This logic is ensured by the original code in very
ambigious way.  For example, currently acpi_tb_delete_table() is invoked in
some place to perform an uninstallation while it is invoked in other place
to perform an invalidation.  They happen to work just because no one enters
the penalty where the 2 behaviours are not equivalent.

The naming cleanups are made in this patch:
A. For installation and validation:
   There is code setting struct acpi_table_desc.Pointer first and delete it
   immediately to keep the descriptor's state as "INSTALLED" during the
   installation.  This patch implements this in more direct way.  After
   applying it, struct acpi_table_desc.Pointer will never be set in
   acpi_tb_install_table() and acpi_tb_override_table() as they are the only
   functions invoked during acpi_initialize_tables(). This is achieved by:
1. Rename acpi_tb_verify_table() to acpi_tb_validate_table() to clarify this
   change.
2. Rename acpi_tb_table_override() to acpi_tb_override_table() to keep nameing
   consistencies as other APIs (verb. Table).
3. Stops setting struct acpi_table_desc.Pointer in acpi_tb_install_table() and
   acpi_tb_table_override().
4. Introduce acpi_tb_acquire_table() to acquire the table pointer that is not
   maintained in the struct acpi_table_desc of the global root table list and
   rewrite acpi_tb_validate_table() using this new function to reduce
   redundancies.
5. Replace the table pointer using the overridden table pointer in
   acpi_tb_add_table(). As acpi_tb_add_table() is not invoked during early boot
   stage, tables returned from this functions should be "VALIDATED".  As
   acpi_tb_override_table() is modified by this patch to return a "INSTALLED"
   but not "VALIDATED" descriptor, to keep acpi_tb_add_table() unchanged,
   struct acpi_table_desc.Pointer is filled in acpi_tb_add_table().
B. For invalidation and uninstallation:
   The original code invalidate table by invoking acpi_tb_delete_table() here
   and there, but actually this function should only be used to uninstall
   tables.  This can work just because its invocations are equivalent to
   invalidation in some cases.
   This patch splits acpi_tb_delete_table() into acpi_tb_invalidate_table() and
   acpi_tb_uninstall_table() and cleans up the hidden logic using the new
   APIs.  This is achieved by:
1. Rename acpi_tb_delete_table() to acpi_tb_uninstall_table() as it is mainly
   called before resetting struct acpi_table_desc.Address.  Thus the table
   descriptor is in "not INSTALLED" state.  This patch enforces this by
   setting struct acpi_table_desc.Address to NULL in this function.
2. Introduce acpi_tb_invalidate_table() to be the reversal of
   acpi_tb_validate_table() and invoke it in acpi_tb_uninstall_table().
3. Introduce acpi_tb_release_table() to release the table pointer that is not
   maintained in acpi_gbl_root_table_list and rewrite acpi_tb_invalidate_table()
   using this new function to reduce redundancies.

After cleaning up, the maintainability of the internal APIs are also
improved:
1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to
                       ACPI_TABLE_ORIGIN_xxx flags.
2. acpi_tb_release_table: Release struct acpi_table_header according to
                       ACPI_TABLE_ORIGIN_xxx flags.
3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to
                       ACPI_TABLE_ORIGIN_xxx flags.
4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to
                         ACPI_TABLE_ORIGIN_xxx flags.
5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to
                        ACPI_TABLE_ORIGIN_xxx flags.
6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to
                          ACPI_TABLE_ORIGIN_xxx flags.
7. acpi_tb_override_table: Replace struct acpi_table_desc.Address and
                        struct acpi_table_desc.Flags.  It only happens in
                        "INSTALLED" state.

The patch has been unit tested in acpi_exec by:
1. Initializing;
2. Executing exc_tbl ASLTS tests;
3. Executing "Load" command.
So that all original acpi_tb_install_table() and acpi_tb_override_table()
invocations are covered.

Known Issues:
1. Cleanup acpi_tb_add_table() to Kill Code Redundancies
   Current implementation in acpi_tb_add_table() is not very clean, further
   patch can rewrite acpi_tb_add_table() with ordered acpi_tb_install_table(),
   acpi_tb_override_table() and acpi_tb_validate_table(). It is not done in this
   patch so that it is easy for the reviewers to understand the changes in
   this patch.

additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR,
SPMI, TCPA, and WDRT. With this support, all current and
known ACPI tables are now defined in the ACPICA headers and
are available for use by device drivers and other software.

Implemented support to allow tables that contain ACPI
names with invalid characters to be loaded. Previously,
this would cause the table load to fail, but since
there are several known cases of such tables on
existing machines, this change was made to enable
ACPI support for them. Also, this matches the
behavior of the Microsoft ACPI implementation.

Fixed a couple regressions introduced during the memory
optimization in the 20060317 release. The namespace
node definition required additional reorganization and
an internal datatype that had been changed to 8-bit was
restored to 32-bit. (Valery Podrezov)

Fixed a problem where a null pointer passed to
acpi_ut_delete_generic_state() could be passed through
to acpi_os_release_object which is unexpected. Such
null pointers are now trapped and ignored, matching
the behavior of the previous implementation before the
deployment of acpi_os_release_object().  (Valery Podrezov,
Fiodor Suietov)

Fixed a memory mapping leak during the deletion of
a SystemMemory operation region where a cached memory
mapping was not deleted. This became a noticeable problem
for operation regions that are defined within frequently
used control methods. (Dana Meyers)

Reorganized the ACPI table header files into two main
files: one for the ACPI tables consumed by the ACPICA core,
and another for the miscellaneous ACPI tables that are
consumed by the drivers and other software. The various
FADT definitions were merged into one common section and
three different tables (ACPI 1.0, 1.0+, and 2.0)
