Linus Torvalds c958423470 Tracing updates for 5.12
- Update to the way irqs and preemption is tracked via the trace event PC field
 
  - Fix handling of unregistering event failing due to allocate memory.
    This is only triggered by failure injection, as it is pretty much guaranteed
    to have less than a page allocation succeed.
 
  - Do not show the useless "filter" or "enable" files for the "ftrace" trace
    system, as they have no effect on doing anything.
 
  - Add a warning if kprobes are registered more than once.
 
  - Synthetic events now have their fields parsed by semicolons.
    Old formats without semicolons will still work, but new features will
    require them.
 
  - New option to allow trace events to show %p without hashing in trace file.
    The trace file can only be read by root, and reading the raw event buffer
    did not have any pointers hashed, so this does not expose anything new.
 
  - New directory in tools called tools/tracing, where a new tool that reads
    sequential latency reports from the ftrace latency tracers.
 
  - Other minor fixes and cleanups.
