 "A couple of platforms have some last-minute fixes, in particular:

   - riscv gets some fixes for noncoherent DMA on the renesas and thead
     platforms and dts fix for SPI on the visionfive 2 board

   - Qualcomm Snapdragon gets three dts fixes to address board specific
     regressions on the pmic and gpio nodes

   - Rockchip platforms get multiple dts fixes to address issues on the
     recent rk3399 platform as well as the older rk3128 platform that
     apparently regressed a while ago.

   - TI OMAP gets some trivial code and dts fixes and a regression fix
     for the omap1 ams-delta modem

   - NXP i.MX firmware has one fix for a use-after-free but in its error
     handling"

Pull EFI fixes from Ard Biesheuvel:
 "The boot_params pointer fix uses a somewhat ugly extern struct
  declaration but this will be cleaned up the next cycle.

   - don't try to print warnings to the console when it is no longer
     available

   - fix theoretical memory leak in SSDT override handling

   - make sure that the boot_params global variable is set before the
     KASLR code attempts to hash it for 'randomness'

   - avoid soft lockups in the memory acceptance code"

  efi/unaccepted: Fix soft lockups caused by parallel memory acceptance
  x86/boot: efistub: Assign global boot_params variable
  efi: fix memory leak in krealloc failure handling
  x86/efistub: Don't try to print after ExitBootService()

Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.

The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.

To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.

A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.

Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.

Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.

The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

[ardb: drop unnecessary cpu_relax() call]
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

Now that the x86 EFI stub calls into some APIs exposed by the
decompressor (e.g., kaslr_get_random_long()), it is necessary to ensure
that the global boot_params variable is set correctly before doing so.

Note that the decompressor and the kernel proper carry conflicting
declarations for the global variable 'boot_params' so refer to it via an
alias to work around this.

In the previous code, there was a memory leak issue where the
previously allocated memory was not freed upon a failed krealloc
operation. This patch addresses the problem by releasing the old memory
before setting the pointer to NULL in case of a krealloc failure. This
ensures that memory is properly managed and avoids potential memory
leaks.

setup_e820() is executed after UEFI's ExitBootService has been called.
This causes the firmware to throw an exception because the Console IO
protocol is supposed to work only during boot service environment. As
per UEFI 2.9, section 12.1:

 "This protocol is used to handle input and output of text-based
 information intended for the system user during the operation of code
 in the boot services environment."

So drop the diagnostic warning from this function. We might add back a
warning that is issued later when initializing the kernel itself.

 "These are the latest bug fixes that have come up in the soc tree. Most
  of these are fairly minor. Most notably, the majority of changes this
  time are not for dts files as usual.

   - Updates to the addresses of the broadcom and aspeed entries in the
     MAINTAINERS file.

   - Defconfig updates to address a regression on samsung and a build
     warning from an unknown Kconfig symbol

   - Build fixes for the StrongARM and Uniphier platforms

   - Code fixes for SCMI and FF-A firmware drivers, both of which had a
     simple bug that resulted in invalid data, and a lesser fix for the
     optee firmware driver

   - Multiple fixes for the recently added loongson/loongarch "guts" soc
     driver

   - Devicetree fixes for RISC-V on the startfive platform, addressing
     issues with NOR flash, usb and uart.

   - Multiple fixes for NXP i.MX8/i.MX9 dts files, fixing problems with
     clock, gpio, hdmi settings and the Makefile

   - Bug fixes for i.MX firmware code and the OCOTP soc driver

   - Multiple fixes for the TI sysc bus driver

   - Minor dts updates for TI omap dts files, to address boot time
     warnings and errors"
