The patch titled kernel/kprobes.c: don't pad kretprobe_table_locks[] on uniprocessor builds has been removed from the -mm tree. Its filename was kernel-kprobesc-dont-pad-kretprobe_table_locks-on-uniprocessor-builds.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: kernel/kprobes.c: don't pad kretprobe_table_locks[] on uniprocessor builds From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> We only need the cacheline padding on SMP kernels.
