| H A D | sync_core.h | bf9c912f Thu Aug 06 22:28:33 CDT 2020 Ricardo Neri <ricardo.neri-calderon@linux.intel.com> x86/cpu: Use SERIALIZE in sync_core() when available
The SERIALIZE instruction gives software a way to force the processor to
complete all modifications to flags, registers and memory from previous
instructions and drain all buffered writes to memory before the next
instruction is fetched and executed. Thus, it serves the purpose of
sync_core(). Use it when available.
