Introduce efi_get_kimg_kaslr_address() helper to compute the preferred
kernel image load address dynamically when CONFIG_RANDOMIZE_BASE is
enabled. The function derives a random offset by using the EFI-provided
randomness combined with the timer tick value, and constrains it within
CONFIG_RANDOMIZE_BASE_MAX_OFFSET.

Update EFI_KIMG_PREFERRED_ADDRESS to call this helper so that the EFI
stub can select a randomized load address when KASLR is active, while
preserving the original base address behavior when KASLR is disabled or
"nokaslr" is specified.

Note: LoongArch can't KASLR for hibernation, so set efi_nokaslr to true
if "resume=<devname>" is explicitly specified in cmdline.

The LTE enabled version of the IdeaPad Duet 3 10IGL5 needs the
same quirk as the non-LTE version. As these are the only two
IdeaPad Duet 3 10IGL5 versions, we can safely use non exact matching.

Tested on a IdeaPad Duet 3 10IGL5-LTE.

  5894cf571e14 ("acpi/prmt: Use EFI runtime sandbox to invoke PRM handlers")

ACPI PRM calls are delegated to a workqueue which runs in a kernel
thread, making it easier to detect and mitigate faulting memory accesses
performed by the firmware.

Rafael reports that such PRM accesses may occur before efisubsys_init()
executes, which is where the workqueue is allocated, leading to NULL
pointer dereferences. Since acpi_init() [which triggers the early PRM
accesses] executes as a subsys_initcall() as well, and has its own
dependencies that may be sensitive to initcall ordering, deferring
acpi_init() is not an option.

So instead, split off the workqueue allocation into its own postcore
initcall, as this is the only missing piece to allow EFI runtime calls
to be made. This ensures that EFI runtime call (including PRM calls) are
accessible to all code running at subsys_initcall() level.

PSCI specification defines the SYSTEM_SUSPEND feature which enables the
firmware to implement the suspend to RAM (S2RAM) functionality by
transitioning the system to a deeper low power state. When the system
enters such state, the power to the peripheral devices might be removed. So
the respective device drivers must prepare for the possible removal of the
power by performing actions such as shutting down or resetting the device
in their system suspend callbacks.

The Linux PM framework allows the platform drivers to convey this info to
device drivers by calling the pm_set_suspend_via_firmware() and
pm_set_resume_via_firmware() APIs.

Hence, if the PSCI firmware supports SYSTEM_SUSPEND feature, call the above
mentioned APIs in the psci_system_suspend_begin() and
psci_system_suspend_enter() callbacks.

ffa_sched_recv_cb_update() used list_for_each_entry_safe() to search for
a matching partition and then tested the iterator against NULL. That is
not a valid end-of-list check for circular lists and can fall through
with an invalid pointer. Use a normal iterator and detect the not-found
case correctly before touching the partition state.

Both notification handlers currently look up a notifier callback under
notify_lock, drop the lock, and then dereference the returned
notifier entry. A concurrent unregister can delete and free that
entry in the gap, leaving the handler to dereference stale memory.

Copy the callback pointer and callback data while notify_lock is
still held and invoke the callback only after the lock is dropped.
This keeps the existing callback execution model while removing the
use-after-free window in both the framework and non-framework
notification paths.

Commit 83210251fd70 ("firmware: arm_ffa: Use the correct buffer size during
RXTX_MAP") advertises PAGE_ALIGN(rxtx_bufsz) to firmware when mapping the
buffers but the driver continues to stores the minimum FF-A buffer size
in drv_info->rxtx_bufsz which is used elsewhere in the driver.

Align the size before storing it so that the allocation, validation and
FFA_RXTX_MAP all use the same buffer size.
