* use-after-free in sctp_do_8_2_transport_strike

* SL7.9 - [Regression] Kernel test failed during CPU polarization test -
lscpu, chcpu - LPAR

* SL 7, block: Crash in blk_mq_rq_timed_out() when dereferencing NULL
request->q pointer

* qla2xxx: Qlogic double completion races during error handling are still
not fixed and this will also  be a SL8+ exposure

* kernel 3.10.0-1160.80.1.el7.x86_64 on Xeon E55xx crashes upon KVM
startup

* Guest's time jumped forward by 12 minutes _after_ live-migration
