This patch set adds support for ARM SPE to track memory accesses and fixes issues in mem_sampling: - Add ARM SPE support for memory access tracking. - Prevent mem_sampling from enabling if SPE initialization fails. - Fix inaccurate sampling during NUMA balancing and DAMON. These changes improve memory sampling accuracy and stability on ARM systems.
