Linus Torvalds 58ca241587 Tracing updates for 5.15:
- Simplifying the Kconfig use of FTRACE and TRACE_IRQFLAGS_SUPPORT
 
  - bootconfig now can start histograms
 
  - bootconfig supports group/all enabling
 
  - histograms now can put values in linear size buckets
 
  - execnames can be passed to synthetic events
 
  - Introduction of "event probes" that attach to other events and
    can retrieve data from pointers of fields, or record fields
    as different types (a pointer to a string as a string instead
    of just a hex number)
 
  - Various fixes and clean ups
