+Commit 004172bdad64432 (sched/core: Remove unnecessary #include
+headers) removed the inclusion of asm/paravirt.h which is used to get
+declarations of paravirt_steal_rq_enabled and paravirt_steal_clock.  It
+is implicitly included on but not on arm and arm64 breaking the build if
+paravirtualization is used.  Since things from that header are used
+directly fix the build by putting the direct inclusion back.
