Linux 5.12-rc7
to receive an ACPI fix for 5.12-rc8.
This restores the initrd-based ACPI table override functionality
broken by one of the recent fixes.
Thanks!

Commit 1a1c130ab757 ("ACPI: tables: x86: Reserve memory occupied by
ACPI tables") attempted to address an issue with reserving the memory
occupied by ACPI tables, but it broke the initrd-based table override
mechanism relied on by multiple users.

Applied as 5.12-rc material, thanks!
Hi,
This series simplifies acpi_bus_check_add() and related code.
It mostly is not expected to alter functionality, except for patch [4/5] that
unifies the handling of device and processor objects.
Please refer to the patch changelogs for details.
Thanks!
From: Rafael J. Wysocki
There is only one caller of acpi_bus_type_and_status() which is
acpi_bus_check_add(), so fold the former into the latter and use
the observation that the initial status of the device is
ACPI_STA_DEFAULT in all cases except for ACPI_BUS_TYPE_PROCESSOR
to simplify the code
From: Rafael J. Wysocki
Rearrange the checks in acpi_bus_check_add() to avoid checking
the "type" twice and take "check_dep" into account only for
ACPI_TYPE_DEVICE objects.
No intentional functional impact.

From: Rafael J. Wysocki
Move the initial status check for ACPI_BUS_TYPE_PROCESSOR objects
into acpi_add_single_object() so it is not necessary to pass the
"sta" argument to it, get rid of that argument from there and update
the callers of that function accordingly.
No intentional
From: Rafael J. Wysocki
Use the observation that the initial status check for
ACPI_BUS_TYPE_PROCESSOR objects can be carried out in the same way
as for ACPI_BUS_TYPE_DEVICE objects and it is not necessary to fail
acpi_add_single_object() if acpi_bus_get_status_handle() returns an
error
From: Rafael J. Wysocki
Notice that it is not necessary to call acpi_get_object_info() from
acpi_add_single_object() in order to pass the pointer returned by it
to acpi_init_device_object() and from there to acpi_set_pnp_ids().
It is more straightforward to call acpi_get_object_info() from

Because pstate.max_freq is always equal to the product of

This way the information can be read later on even though mapping to

Make the tick_nohz_get_next_hrtimer() kerneldoc comment state clearly
that the function may return negative numbers.

Hi All,
As follows from the discussion triggered by the patch at
https://lore.kernel.org/lkml/20210311123708.23501-2-frede...@kernel.org/
the cpuidle governors using tick_nohz_get_sleep_length() assume it to always
return positive values which is not correct in general.
To address this issues,

If PCI_D3cold is passed to acpi_pci_set_power_state() as the second
argument and there is no ACPI D3cold support for the given device,
the debug message printed by that function will state that the
device power state has been changed to D3cold, while in fact
