Given ESM kernel only accepts CVE patches, will only send patches against Mantic
[Impact] The updated LTP has added proc_sched_rt01 testcase which can't pass since several commits are missed from kernel side.

Jammy: stable v5.15.150 includes the three commits. Focal: master-next has include them after update to v5.4.270 Bionic: all the three commits are needed. [Test case] Run LTP update 20240312 to check the log of proc_sched_rt01. [Regression potential] Low risk since these content are existed in upstream for a while.
