    Pull tracing updates from Steven Rostedt:
     "Updates for tracing and bootconfig:
    
       - Add support for "bool" type in synthetic events
    
       - Add per instance tracing for bootconfig
    
       - Support perf-style return probe ("SYMBOL%return") in kprobes and
         uprobes
    
       - Allow for kprobes to be enabled earlier in boot up
    
       - Added tracepoint helper function to allow testing if tracepoints
         are enabled in headers
    
       - Synthetic events can now have dynamic strings (variable length)
    
       - Various fixes and cleanups"
