Merge tag 'sched_ext-for-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
- scx_bpf_now() added so that BPF scheduler can access the cached
timestamp in struct rq to avoid reading TSC multiple times within a
locked scheduling operation.
- Minor updates to the built-in idle CPU selection logic.
- tool/sched_ext updates and other misc changes.
