| H A D | sync_core.h | e61938a9 Mon Jan 29 14:20:15 CST 2018 Mathieu Desnoyers <mathieu.desnoyers@efficios.com> locking: Introduce sync_core_before_usermode()
Introduce an architecture function that ensures the current CPU
issues a core serializing instruction before returning to usermode.
This is needed for the membarrier "sync_core" command.
Architectures defining the sync_core_before_usermode() static inline
need to select ARCH_HAS_SYNC_CORE_BEFORE_USERMODE.
