Scheduler updates for 9.3
JIRA: https://issues.redhat.com/browse/RHEL-282
Tested: With scheduler stress tests. Perf QE is running performance regression tests.
Update the kernel's core scheduler and related code with fixes and minor changes from
the upstream kernel. This will sync up to roughly linux v6.3-rc6. Added a couple of
cpumask things which fit better here.
