Linus Torvalds 76bfd3de34 tracing updates for 5.19:
- The majority of the changes are for fixes and clean ups.
 
 Noticeable changes:
 
 - Rework trace event triggers code to be easier to interact with.
 
 - Support for embedding bootconfig with the kernel (as suppose to having it
   embedded in initram). This is useful for embedded boards without initram
   disks.
 
 - Speed up boot by parallelizing the creation of tracefs files.
 
 - Allow absolute ring buffer timestamps handle timestamps that use more than
   59 bits.
 
 - Added new tracing clock "TAI" (International Atomic Time)
 
 - Have weak functions show up in available_filter_function list as:
    __ftrace_invalid_address___<invalid-offset>
   instead of using the name of the function before it.
