Linux 7.2 Released: Cache-aware scheduling, sub-schedulers, and Raspberry Pi GPU power management

Linux 7.2 was tagged and released this week, one of the busiest cycles ever, only beaten by 6.7. Highlights include cache-aware scheduling, improvements to MGLRU, the concept of sub-schedulers for sched_ext, and automatic creation of multi-size transparent hugepages. Igalia contributed the DRM scheduler fair policy, which is opt-in due to a last-minute regression, and runtime power management for Raspberry Pi 4 and 5 GPUs, reducing idle power consumption. The kernel also fixes a 14-year-old futex bug and improves sched_ext observability.
