  arm_mpam: Check whether the config array is allocated before destroying it (2026-05-14 09:52:05 +0100)

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

 - Fix NULL dereference and a false-positive warning when the driver
   probes hardware with surprising version numbers

 - Fix writing values to the wrong registers when probing
   cache-utilisation counters. Replace 'NRDY' probing with a version
   that is robust for platforms where the bit is writeable by both
   hardware and software

----------------------------------------------------------------
Ben Horgan (3):
      arm_mpam: Fix monitor instance selection when checking for hardware NRDY
      arm_mpam: Pretend that NRDY is always hardware managed
      arm_mpam: Improve check for whether or not NRDY is hardware managed

James Morse (2):
      arm_mpam: Fix false positive assert failure during mpam_disable()
      arm_mpam: Check whether the config array is allocated before destroying it
