+Subject: [PATCH 3/6] ARM: config: omap: Disable extra debug options
+
+LOCK debug, SCHED debug, PREEMPT debug are very expensive operations and
+always in fast path of kernel operations. These are typical kernel development
+options and should be disabled in production kernel builds.
+
+Also enable JUMP_LABEL to take advantage of compiler optimisations.
+
+Created using typical 'savedefconfig' method. Hence you see some crypto
+option noise which unrelated and no impact on the end config.
