The following commit has been merged into the sched/core branch of tip: Commit-ID: 33c64734be3461222a8aa27d3dadc477ebca62de Gitweb: https://git.kernel.org/tip/33c64734be3461222a8aa27d3dadc477ebca62de Author: Mark Rutland <mark.rutland@xxxxxxx> AuthorDate: Mon, 14 Feb 2022 16:52:13 Committer: Peter Zijlstra <peterz@xxxxxxxxxxxxx> CommitterDate: Sat, 19 Feb 2022 11:11:08 +01:00 sched/preempt: Decouple HAVE_PREEMPT_DYNAMIC from GENERIC_ENTRY Now that the enabled/disabled states for the preemption functions are declared alongside their definitions, the core PREEMPT_DYNAMIC logic is no longer tied to GENERIC_ENTRY, and can safely be selected so long as an architecture provides enabled/disabled states for irqentry_exit_cond_resched(). Make it possible to select HAVE_PREEMPT_DYNAMIC without GENERIC_ENTRY. For existing users of HAVE_PREEMPT_DYNAMIC there should be no functional change as a result of this patch.
