It is reported that there are buggy BIOSes in the world: AMI uses an XSDT
compiler for early BIOSes, this compiler will generate XSDT with a NULL
entry.  The affected BIOS versions are "AMI BIOS F2-F4".

Original solution on Linux is to use an alternative heathy root table
instead of the ill one.  This commit is:
  Commit: 671cc68d
  Subject: ACPICA: Back port and refine validation of the XSDT root table.

This is an example of such XSDT dumped from B85-HD3 (AMI F3 BIOS):

[06Ch 0108   8]       ACPI Table Address   9 : 0000000000000000

But according to the bug report, the XSDT in fact is not broken. In the
above XSDT, ACPI Table Address 1-8 contains the same value as RSDT.  The
differences can only be seen on the following 2 entries:
1. The first entry points to a FADT whose Revision is 5 while the first
   entry in RSDT points to a FADT whose Revision is 2.
   The FADT dumped from the address indicated by the first entry of XSDT:
    FACP @ 0x00000000BA5F8180
      0000: 46 41 43 50 0C 01 00 00<05>4B 41 4C 41 53 4B 41  FACP.....KALASKA
      ...
   The FADT dumped from the address indicated by the first entry of RSDT:
    FACP @ 0x00000000BA5ED0F0
      0000: 46 41 43 50 84 00 00 00<02>A7 41 4C 41 53 4B 41  FACP......ALASKA
      ...
2. The last entry is a NULL terminator.
According to the test result, the Revision 5 FADT is accessible.  Thus the
original solution turns out to be a work around that is preventing the
higher revision tables to be used for such platforms (they are all x86-64
platforms, and should use XSDT and higher revision FADT).

This patch offers a new solution, where a sanity check is performed before
installing a table address from XSDT. If the entry is NULL, it is simply
discarded.

Note that, this patch doesn't remove the original solution, so for Linux
kernel, this commit is actually a no-op, but it allows acpidump to be
working on such platforms. By doing so, we allow another easy revertable
commit to enable this feature so that when that commit is reverted, the
useful sanity check will not be affected. Lv Zheng.

This patch refines ACPI_TABLE_ORIGIN_xxx flags.  No functional changes.

The previous commits have introduced the following internal APIs:
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.
It thus detects that the ACPI_TABLE_ORIGIN_UNKNOWN is redundant to
ACPI_TABLE_ORIGIN_OVERRIDE.

The ACPI_TABLE_ORIGIN_xxTERN_VIRTUAL flags are named as VIRTUAL in order
not to confuse with x86 logical address, this patch also renames all
"logical override" into "virtual override".

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.

When table is overridden or reloaded, acpi_tb_delete_table() is called where
struct acpi_table_desc.Pointer will be NULL.  It thus is impossible for virtual
addressed tables to obtain the .Pointer again in acpi_tb_verify_table().

This patch stores virtual table addresses  (ACPI_TABLE_ORIGIN_ALLOCATED,
ACPI_TABLE_ORIGIN_UNKNOWN, ACPI_TABLE_ORIGIN_OVERRIDE) in the
struct acpi_table_desc.Address field and refills the struct acpi_table_desc.Pointer
using these addresses in acpi_tb_verify_table(). Note that if a table with
ACPI_TABLE_ORIGIN_ALLOCATED set is actually freed, the .Address field
should be invalidated and thus must be replaced with NULL to avoid wrong
future validations occuring in acpi_tb_verify_table().

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.

Move initialization of DSDT pointer. Emit address of DSDT
in the dump of both table headers (good/bad DSDT).
Now handles the case where the root table can be reallocated,
which would invalidate the original pointer.

Optionally copy the entire DSDT to local memory (instead of
simply mapping it.) There are some BIOSs that corrupt or replace
the original DSDT, creating the need for this option. Default is
FALSE, do not copy the DSDT.

This change adds support to detect a DSDT that has been corrupted
and/or replaced from outside the OS (by firmware). This is
typically catastrophic for the system, but has been seen on
some machines.

Function acpi_tb_print_table_header. Some ACPI tables contain
non-printable characters in one of the string fields of the the
header - Signature, OemId, OemTableId, or CompilerId. Invalid
characters are replaced by '?'. ACPICA BZ 788.

Previously, the table override mechanism was implemented for the
DSDT only. Now, any table in the RSDT/XSDT can be replaced by
the host OS. (including the DSDT).

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).
