sched_ext: Merge branch 'for-6.15-fixes' into for-6.16

Pull for-6.15-fixes to receive:

 e776b26e3701 ("sched_ext: Remove cpu.weight / cpu.idle unimplemented warnings")

which conflicts with:

 1a7ff7216c8b ("sched_ext: Drop "ops" from scx_ops_enable_state and friends")

The former removes code updated by the latter. Resolved by removing the
updated section.
