  arm64: Fix cleared E0POE bit after cpu_suspend()/resume() (2026-01-09 10:41:45 +0000)

----------------------------------------------------------------
arm64 fixes:

 - Do not return false if !preemptible() in current_in_efi(). EFI
   runtime services can now run with preemption enabled

 - Fix uninitialised variable in the arm MPAM driver, reported by sparse

 - Fix partial kasan_reset_tag() use in change_memory_common() when
   calculating page indices or comparing ranges

 - Save/restore TCR2_EL1 during suspend/resume, otherwise the E0POE bit
   is lost

----------------------------------------------------------------
Ben Horgan (2):
      arm64/efi: Don't fail check current_in_efi() if preemptible
      arm_mpam: Stop using uninitialized variables in __ris_msmon_read()

Jiayuan Chen (1):
      arm64: mm: Fix incomplete tag reset in change_memory_common()

Yeoreum Yun (1):
      arm64: Fix cleared E0POE bit after cpu_suspend()/resume()
