778b94d7ac ACPI: platform_profile: Add support for hidden choices
When two drivers don't support all the same profiles the legacy interface
only exports the common profiles.

This causes problems for cases where one driver uses low-power but another
uses quiet because the result is that neither is exported to sysfs.

To allow two drivers to disagree, add support for "hidden choices".
Hidden choices are platform profiles that a driver supports to be
compatible with the platform profile of another driver.

f818227a2f ACPI: GTDT: Relax sanity checking on Platform Timers array count
Perhaps unsurprisingly there are some platforms where the GTDT isn't
quite right and the Platforms Timer array overflows the length of the
overall table.

While the recently-added sanity checking isn't wrong, it makes it
impossible to boot the kernel on offending platforms. Try to hobble
along and limit the Platform Timer count to the bounds of the table.

7f5704b6a1 ACPI: PRM: Remove unnecessary strict handler address checks
Commit 088984c8d5 ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM
handler and context") added unnecessary strict handler address checks,
causing the PRM module to fail in translating memory error addresses.

Both static data buffer address and ACPI parameter buffer address may
be NULL if they are not needed, as described in section 4.1.2 PRM Handler
Information Structure of Platform Runtime Mechanism specification [1].

Here are two examples from real hardware:

ab930483ec ACPI: property: Fix return value for nval == 0 in acpi_data_prop_read()
While analysing code for software and OF node for the corner case when
caller asks to read zero items in the supposed to be an array of values
I found that ACPI behaves differently to what OF does, i.e.

 1. It returns -EINVAL when caller asks to read zero items from integer
    array, while OF returns 0, if no other errors happened.

 2. It returns -EINVAL when caller asks to read zero items from string
    array, while OF returns -ENODATA, if no other errors happened.

Amend ACPI implementation to follow what OF does.

The root cause is acpi_enable_all_wakeup_gpes() uses a mutex to protect
acpi_hw_enable_all_wakeup_gpes(), and acpi_ut_acquire_mutex() may cause
a thread switch. Since there is no longer concurrent execution during
loongarch_acpi_suspend(), we can call acpi_hw_enable_all_wakeup_gpes()
directly in enable_gpe_wakeup().

The solution is similar to commit 22db06337f ("ACPI: sleep: Avoid
breaking S3 wakeup due to might_sleep()").

63db8170bf mm/fake-numa: allow later numa node hotplug
Current fake-numa implementation prevents new Numa nodes to be later
hot-plugged by drivers.  A common symptom of this limitation is the "node
<X> was absent from the node_possible_map" message by associated warning
in mm/memory_hotplug.c: add_memory_resource().

This comes from the lack of remapping in both pxm_to_node_map[] and
node_to_pxm_map[] tables to take fake-numa nodes into account and thus
triggers collisions with original and physical nodes only-mapping that had
been determined from BIOS tables.

This patch fixes this by doing the necessary node-ids translation in both
pxm_to_node_map[]/node_to_pxm_map[] tables.  node_distance[] table has
also been fixed accordingly.


Details:

When trying to use fake-numa feature on our system where new Numa nodes
are being "hot-plugged" upon driver load, this fails with the following
type of message and warning with stack :

node 8 was absent from the node_possible_map WARNING: CPU: 61 PID: 4259 at
mm/memory_hotplug.c:1506 add_memory_resource+0x3dc/0x418

This issue prevents the use of the fake-NUMA debug feature with the
system's full configuration, when it has proven to be sometimes extremely
useful for performance testing of multi-tasked, memory-bound applications,
as it enables better isolation of processes/ranks compared to fat NUMA
nodes.

Usual numactl output after driver has “hot-plugged”/unveiled some
new Numa nodes with and without memory :

     to avoid the need to quirk which handler takes precedence
   - Support reporting "custom" profile for cases where the current
     profile is ambiguous or when settings tweaks are done outside the
     pre-defined profile
   - Abstract and layer platform_profile API better using the class_dev
     and drvdata

8f62ca9c33 ACPI: x86: Add skip i2c clients quirk for Vexia EDU ATLA 10 tablet 5V
The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.

Both ship with Android 4.4 as factory OS and have the usual broken DSDT
issues for x86 Android tablets.

Add a quirk to skip ACPI I2C client enumeration for the 5V version to
complement the existing quirk for the 9V version.

Pull ACPI updates from Rafael Wysocki:
 "The most significant change here is replacing msleep() in
  acpi_os_sleep() with usleep_range() to reduce spurious sleep time due
  to timer inaccuracy which may spectacularly reduce the duration of
  system suspend and resume transitions on some systems.

  All of the other changes fall into the fixes and cleanups category
  this time.

  Specifics:

   - Use usleep_range() instead of msleep() in acpi_os_sleep() to reduce
     excessive delays due to timer inaccuracy, mostly affecting system
     suspend and resume (Rafael Wysocki)

   - Use str_enabled_disabled() string helpers in the ACPI tables
     parsing code to make it easier to follow (Sunil V L)

   - Update device properties parsing on systems using ACPI so that data
     firmware nodes resulting from _DSD evaluation are treated as
     available in firmware nodes walks (Sakari Ailus)

   - Fix missing guid_t declaration in linux/prmt.h (Robert Richter)

   - Update the GHES handling code to follow the global panic= policy
     instead of overriding it by force-rebooting the system after a
     fatal HW error has been reported (Borislav Petkov)

   - Update messages printed by the ACPI battery driver to always refer
     to driver extensions as "hooks" to avoid confusion with similar
     functionality in the power supply subsystem in the future (Thomas
     Weißschuh)

   - Fix .probe() error path cleanup in the ACPI fan driver to avoid
     memory leaks (Joe Hattori)

   - Constify 'struct bin_attribute' in some places in the ACPI
     subsystem and mark it as __ro_after_init in one place to prevent
     binary blob attributes from being updated (Thomas Weißschuh)

   - Add empty stubs for several ACPI-related symbols so that they can
     be used when CONFIG_ACPI is unset and use them for removing
     unnecessary conditional compilation from the ipu-bridge driver
     (Ricardo Ribalda)"
