Linus Torvalds 16b70698aa sched_ext: Fixes for v6.16-rc1
Two fixes in the built-in idle selection helpers.
 
 - Fix prev_cpu handling to guarantee that idle selection never returns a CPU
   that's not allowed.
 
 - Skip cross-node search when !NUMA which could lead to infinite looping due
   to a bug in NUMA iterator.
