5607eece84 Documentation: Tweak text about Zero Latency Interrupts 
This is a follow-up to 366c8a5d94 (PR-15102).

* Documentation/guides/zerolatencyinterrupts.rst
  (Title): Make title case consistent.
  (Getting Back into the Game, Maskable Nested Interrupts): Clarify discussion
   about priorities.
  (Cortex-M3/4 Implementation): The first half of a sentence was deleted in
   366c8a5d9 because the Kconfig that was described there no longer exists:
   CONFIG_ARMV7M_USEBASEPRI. Write a new beginning for this sentence that
   matches current implementation.
  (Disabling the High Priority Interrupt): Change "cannot" to "must not be
   allowed to" to improve clarity.
  (Configuring High Priority Interrupts): Change "to NVIC" to "in NVIC" to
   improve clarity.

95ed02ec22 arm64/qemu: Add 9pfs configuration 
Convenient for qemu debugging and adding ci check

9555f9ff55 arm64/mte: Add support for arm64 mte 
For details, please refer to the kernel's introduction to this at "https://docs.kernel.org/arch/arm64/memory-tagging-extension.html" and Android's introduction to this at "https://source.android.com/docs/security/test/memory-safety/arm-mte"

Of course, there is also the following detailed principle introduction
https://developer.arm.com/-/media/Arm%20Developer%20Community/PDF/Arm_Memory_Tagging_Extension_Whitepaper.pdf

The modification of this patch is only to merge the simplest MTE function support. In the future, the MTE function will be integrated into the kernel to a greater extent, for example, hardware MTE Kasan will be supported in the future.

c6591c0f49 driver/serial: remove return value of up_putc() 
modify the prototype of up_putc(): remove the return value

The architecture code does not care about the return value of up_putc(), so removing it saves two statements:

6657f2abb7 boards/arm/stm32f7: separate nucleo-144 board into individual boards 
nucleo-144 combines 3 different ST boards. This approach is inconsistent with
the support for the rest of the nucleo boards, where each board is in separate folders.
Also nucleo-144 is no longer reserved for STM32F7 chips but other families also use this format.

After this commit nucleo-144 is divided into 3 boards:

- nucleo-f746zg
- nucleo-f767zi
- nucleo-f722ze
