Subject: kselftest:arm64/FVP: arm64_check_buffer_fill - failed on Linux next-20241025

The following kselftest arm64 and FVP failed with Linux next-20241025 on
  - Qemu-arm64
  - FVP

running Linux next-20241025 kernel.

First seen on next-20241025
  Good: next-20241024
  BAD:  next-20241025

 kselftest-arm64, FVP
    * arm64_check_buffer_fill
    * arm64_check_mmap_options
    * arm64_check_child_memory

Anyone have seen these failures ?
