      ACPICA: Mention the LVR bits
      ACPICA: fix I2C LVR item count in the conversion table

Aymeric Wibo (1):
      ACPICA: actypes: Distinguish between D3hot/cold

Daniel Schaefer (1):
      ACPICA: Add modern standby DSM GUIDs

      ACPICA: Add alias node support in namespace handling
      ACPICA: Fix use-after-free in acpi_ds_terminate_control_method()
      ACPICA: validate byte_count in acpi_ps_get_next_package_length()
      ACPICA: add boundary checks in acpi_ps_get_next_field()
      ACPICA: Prevent adding invalid references
      ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op)
      ACPICA: Improve argument parsing in acpi_ps_get_next_simple_arg()

From: Abdelkader Boudih <oss@seuros.com>

When the 64-bit address is set but bit_width is 0, the spec says
the legacy length should be used. That is valid firmware.

Skip the warning if bit_width is 0.

This avoids false warnings like:
  32/64X length mismatch in FADT/gpe0_block: 128/0

Tested on free_BSD 16.0-CURRENT.

From: Akhil R <akhilrajeev@nvidia.com>

For ACPI_RSC_MOVE8, the 'Value' field in struct acpi_rsconvert_info
is the item count count and not a bit position like for the
bitflags. Set 'Value' as '1' to fix this.

Conversion still works coincidentally with '0' because
item_count is not reset between table entries, and the previous
count value was taking effect.

From: Weiming Shi <bestswngs@gmail.com>

acpi_ns_custom_package() unconditionally dereferences the first element
of the package to read the _BIX version number, without checking for
NULL:

    if ((*Elements)->Common.Type != ACPI_TYPE_INTEGER)

When firmware returns a _BIX package whose first element is an
unresolvable reference, ACPICA evaluates that entry to NULL.
acpi_ns_remove_null_elements() does not strip NULL entries for
ACPI_PTYPE_CUSTOM packages (fixed-position format would break if
elements were shifted), so acpi_ns_custom_package() sees the NULL
and causes a crash.

Add a NULL check for the first element (version field) before
dereferencing it. The caller then receives AE_AML_OPERAND_TYPE
instead of crashing.

From: David Laight <david.laight.linux@gmail.com>

The debug code in acpi_ps_delete_parse_tree() uses ("%*.s", level * 4, " ")
to indent traces.

POSIX requires the empty precision be treated as zero, but the kernel treats
is as 'no precision specified'.

Change to ("%*s", level * 4, "") since there is additional whitespace and no
reason to indent by one space when level is zero.
