When serrors=diverse is selected by the user, we will only synchronize the pending SErrors on entry to hypervisor from guest context and exit from guest to hypervisor context. We don't need synchronize SErrors between guest context switch as they would be categorized to Hypervisor generated SErrors in any case. Signed-off-by: Julien Grall <julien.grall@xxxxxxx> Reviewed-by: Stefano Stabellini <sstabellini@xxxxxxxxxx> --- The documentation for the option serrors will be fully reworked in a follow-up patch. But the dsb/isb in the context switch will be removed before the documentation rework. So to avoid any question while reviewing the next patch, drop it now.
