5d6e59665d ACPICA: Use original pointer for virtual origin tables
ACPICA commit dfa3feffa8f760b686207d09dc880cd2f26c72af

Currently the pointer to the table is cast to acpi_physical_address and
later cast back to a pointer to be dereferenced. Whether or not this is
supported is implementation-defined.

On CHERI, and thus Arm's experimental Morello prototype architecture,
pointers are represented as capabilities, which are unforgeable bounded
pointers, providing always-on fine-grained spatial memory safety. This
means that any pointer cast to a plain integer will lose all its
associated metadata, and when cast back to a pointer it will give a
null-derived pointer (one that has the same metadata as null but an
address equal to the integer) that will trap on any dereference. As a
result, this is an implementation where acpi_physical_address cannot be
used as a hack to store real pointers.

Thus, alter the lifecycle of table descriptors. Internal physical tables
keep the current behaviour where only the address is set on install, and
the pointer is set on acquire. Virtual tables (internal and external)
now store the pointer on initialisation and use that on acquire (which
will redundantly set *table_ptr to itself, but changing that is both
unnecessary and overly complicated as acpi_tb_acquire_table is called with
both a pointer to a variable and a pointer to Table->Pointer itself).

This requires propagating the (possible) table pointer everywhere in
order to make sure pointers make it through to acpi_tb_acquire_temp_table,
which requires a change to the acpi_install_table interface. Instead of
taking an ACPI_PHYSADDR_TYPE and a boolean indicating whether it's
physical or virtual, it is now split into acpi_install_table (that takes
an external virtual table pointer) and acpi_install_physical_table (that
takes an ACPI_PHYSADDR_TYPE for an internal physical table address).
This also has the benefit of providing a cleaner API.

0ce792d660 ACPICA: Allow acpi_any_gpe_status_set() to skip one GPE
The check carried out by acpi_any_gpe_status_set() is not precise enough
for the suspend-to-idle implementation in Linux and in some cases it is
necessary make it skip one GPE (specifically, the EC GPE) from the check
to prevent a race condition leading to a premature system resume from
occurring.

For this reason, redefine acpi_any_gpe_status_set() to take the number
of a GPE to skip as an argument.

Commit fdde0ff859 ("ACPI: PM: s2idle: Prevent spurious SCIs from
waking up the system") overlooked the fact that fixed events can wake
up the system too and broke RTC wakeup from suspend-to-idle as a
result.

Fix this issue by checking the fixed events in acpi_s2idle_wake() in
addition to checking wakeup GPEs and break out of the suspend-to-idle
loop if the status bits of any enabled fixed events are set then.

1770093c5b ACPICA: make acpi_load_table() return table index
ACPICA commit d1716a829d19be23277d9157c575a03b9abb7457

For unloading an ACPI table, it is necessary to provide the index of
the table. The method intended for dynamically loading or hotplug
addition of tables, acpi_load_table(), should provide this information
via an optional pointer to the loaded table index.

This patch fixes the table unload function of acpi_configfs.

aa342261bd ACPICA: Remove legacy module-level code support
ACPICA commit 47f5607c204719d9239a12b889df725225098c8f

Module-level code refers to executable ASL code that runs during
table load. This is typically used in ASL to declare named objects
based on a condition evaluated during table load like so:

definition_block(...)
{
  opreation_region (OPR1, system_memory, ...)
  Field (OPR1)
  {
    FLD1, 8 /* Assume that FLD1's value is 0x1 */
  }

  /* The if statement below is referred to as module-level code */

  If (FLD1)
  {
    /* Declare DEV1 conditionally */
    Device (DEV1) {...}
  }

  Device (DEV2)
  {
    ...
  }
}

In legacy module-level code, the execution of the If statement
was deferred after other modules were loaded. The order of
code execution for the table above is the following:

1.) Load OPR1 to the ACPI Namespace
2.) Load FLD1 to the ACPI Namespace (not intended for drivers)
3.) Load DEV2 to the ACPI Namespace
4.) Execute If (FLD1) and load DEV1 if the condition is true

This legacy approach can be problematic for tables that look like the
following:

definition_block(...)
{
  opreation_region (OPR1, system_memory, ...)
  Field (OPR1)
  {
    FLD1, 8 /* Assume that FLD1's value is 0x1 */
  }

  /* The if statement below is referred to as module-level code */

  If (FLD1)
  {
    /* Declare DEV1 conditionally */
    Device (DEV1) {...}
  }

  Scope (DEV1)
  {
    /* Add objects DEV1's scope */
    Name (OBJ1, 0x1234)
  }
}

When loading this in the legacy approach, Scope DEV1 gets evaluated
before the If statement. The following is the order of execution:

1.) Load OPR1 to the ACPI Namespace
2.) Load FLD1 to the ACPI Namespace (not intended for drivers)
3.) Add OBJ1 under DEV1's scope -- ERROR. DEV1 does not exist
4.) Execute If (FLD1) and load DEV1 if the condition is true

The legacy approach can never succeed for tables like this due to the
deferral of the module-level code. Due to this limitation, a new
module-level code was developed. This new approach exeutes if
statements in the order that they appear in the definition block.
With this approach, the order of execution for the above defintion
block is as follows:

1.) Load OPR1 to the ACPI Namespace
2.) Load FLD1 to the ACPI Namespace (not intended for drivers)
3.) Execute If (FLD1) and load DEV1 because the condition is true
4.) Add OBJ1 under DEV1's scope.

Since DEV1 is loaded in the namespace in step 3, step 4 executes
successfully.

This change removes support for the legacy module-level code
execution. From this point onward, the new module-level code
execution will be the official approach.

08930d56c7 ACPICA: Remove acpi_gbl_group_module_level_code and only use acpi_gbl_execute_tables_as_methods instead
acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were
used to enable different table load behavior. The different table
load behaviors are as follows:

A.) acpi_gbl_group_module_level_code enabled the legacy approach where
    ASL if statements are executed after the namespace object has
    been loaded.
B.) acpi_gbl_execute_tables_as_methods is currently used to enable the
    table load to be a method invocation. This meaning that ASL If
    statements are executed in-line rather than deferred until after
    the ACPI namespace has been populated. This is the correct
    behavior and option A will be removed in the future.

We do not support a table load behavior where these variables are
assigned the same value. In otherwords, we only support option A or B
and do not need acpi_gbl_group_module_level_code to enable A. From now on,
acpi_gbl_execute_tables_as_methods == 0 enables option A and
acpi_gbl_execute_tables_as_methods == 1 enables option B.

Note: option A is expected to be removed in the future and option B
will become the only supported table load behavior.

745364533e ACPICA: Introduce acpi_dispatch_gpe()
Introduce acpi_dispatch_gpe() as a wrapper around acpi_ev_detect_gpe()
for checking if the given GPE (as represented by a GPE device handle
and a GPE number) is currently active and dispatching it (if that's
the case) outside of interrupt context.
