    Pull scheduler fixes from Ingo Molnar:

     - Fix spurious failures in rseq self-tests (Mark Brown)

     - Fix rseq rseq::cpu_id_start ABI regression due to TCMalloc's creative
       use of the supposedly read-only field

       The fix is to introduce a new ABI variant based on a new (larger)
       rseq area registration size, to keep the TCMalloc use of rseq
       backwards compatible on new kernels (Thomas Gleixner)

     - Fix wakeup_preempt_fair() for not waking up task (Vincent Guittot)

     - Fix s64 mult overflow in vruntime_eligible() (Zhan Xusheng)
