Commit 32ece31db4df ("ACPI: PM: s2idle: Only retrieve constraints when
needed") attempted to avoid useless evaluation of LPS0 _DSM Function 1
in lps0_device_attach() because pm_debug_messages_on might never be set
(and that is the case on production systems most of the time), but it
turns out that LPS0 _DSM Function 1 is generally problematic on some
platforms and causes suspend issues to occur when pm_debug_messages_on
is set now.

In Linux, LPS0 _DSM Function 1 is only useful for diagnostics and only
in the cases when the system does not reach the deepest platform idle
state during suspend-to-idle for some reason.  If such diagnostics is
not necessary, evaluating it is a loss of time, so using it along with
the other pm_debug_messages_on diagnostics is questionable because the
latter is expected to be suitable for collecting debug information even
during production use of system suspend.

For this reason, add a module parameter called check_lps0_constraints
to control whether or not the list of LPS0 constraints will be checked
in acpi_s2idle_prepare_late_lps0() and so whether or not to evaluate
LPS0 _DSM Function 1 (once) in acpi_s2idle_begin_lps0().

Commit 32ece31db4df ("ACPI: PM: s2idle: Only retrieve constraints
when needed"), that attempted to avoid useless evaluation of LPS0 _DSM
Function 1 in lps0_device_attach(), forgot to add checks for
lps0_device_handle and sleep_no_lps0 to acpi_s2idle_begin_lps0()
where they should be done before calling lpi_device_get_constraints()
or lpi_device_get_constraints_amd().

Add the missing checks.

In ACPI Global System Interrupts (GSIs) are described using a 32-bit
value.

ACPI/PCI legacy interrupts (INTx) parsing code treats GSIs as 'int',
which poses issues if the GSI interrupt value is a 32-bit value with the
MSB set (as required in some interrupt configurations - eg ARM64 GICv5
systems) because acpi_pci_link_allocate_irq() treats a negative gsi
return value as a failed GSI allocation (and acpi_irq_get_penalty()
would trigger an out-of-bounds array dereference if the 'irq' param is
a negative value).

Fix ACPI/PCI legacy INTx parsing by converting variables representing
GSIs from 'int' to 'u32' bringing the code in line with the ACPI
specification and fixing the current parsing issue.

Local variable 'ret' in acpi_pcc_address_space_setup() is currently
declared as 'static'. This can lead to race conditions in a
multithreaded environment.

Remove the 'static' qualifier to ensure that 'ret' will be allocated
directly on the stack as a local variable.

The current implementation overlooks the 'guaranteed_perf'
register in this check.

If the Guaranteed Performance register is located in the PCC
subspace, the function currently attempts to read it without
acquiring the lock and without sending the CMD_READ doorbell
to the firmware. This can result in reading stale data.

   increases the flexibility of KEXEC Handover. Also preparation for LUO

 - "Live Update Orchestrator" (Pasha Tatashin)
   is a major new feature targeted at cloud environments. Quoting the
   cover letter:

      This series introduces the Live Update Orchestrator, a kernel
      subsystem designed to facilitate live kernel updates using a
      kexec-based reboot. This capability is critical for cloud
      environments, allowing hypervisors to be updated with minimal
      downtime for running virtual machines. LUO achieves this by
      preserving the state of selected resources, such as memory,
      devices and their dependencies, across the kernel transition.

      As a key feature, this series includes support for preserving
      memfd file descriptors, which allows critical in-memory data, such
      as guest RAM or any other large memory region, to be maintained in
      RAM across the kexec reboot.

   Mike Rappaport merits a mention here, for his extensive review and
   testing work.
