+Subject: [PATCH 147/195] lockdep: Mark emergency section in lockdep splats
+
+Mark an emergency section within print_usage_bug(), where
+lockdep bugs are printed. In this section, the CPU will not
+perform console output for the printk() calls. Instead, a
+flushing of the console output will triggered when exiting
+the emergency section.
