The patch titled Subject: kernel/smp.c: use '|=' for csd_lock has been removed from the -mm tree. Its filename was kernel-smpc-use-=-for-csd_lock.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: liguang <lig.fnst@xxxxxxxxxxxxxx> Subject: kernel/smp.c: use '|=' for csd_lock csd_lock() uses assignment to data->flags rather than |=. That is not buggy at present because only one bit (CSD_FLAG_LOCK) is defined in call_single_data.flags. But it will become buggy if we later add another flag, so fix it now.
