tracing: create menuconfig for tracing infrastructure
During testing we often use randconfig to test various kernels. The current configuration set up does not give an easy way to disable all tracing with a single config. The case where randconfig would test all tracing disabled is very unlikely. This patch adds a config option to enable or disable all tracing. It is hooked into the tracing menu just like other submenus are done. [ Impact: allow randconfig to easily produce all traces disabled ] Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
