Merge tag 'sched_ext-for-7.0-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext fixes from Tejun Heo:

 - Fix SCX_KICK_WAIT deadlock where multiple CPUs waiting for each other
   in hardirq context form a cycle. Move the wait to a balance callback
   which can drop the rq lock and process IPIs.

 - Fix inconsistent NUMA node lookup in scx_select_cpu_dfl() where
   the waker_node used cpu_to_node() while prev_cpu used
   scx_cpu_node_if_enabled(), leading to undefined behavior when
   per-node idle tracking is disabled.
