Linus Torvalds fefa636d81 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
