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
