Linus Torvalds 79ef0c0014 Tracing updates for 5.16:
- kprobes: Restructured stack unwinder to show properly on x86 when a stack
   dump happens from a kretprobe callback.
 
 - Fix to bootconfig parsing
 
 - Have tracefs allow owner and group permissions by default (only denying
   others). There's been pressure to allow non root to tracefs in a
   controlled fashion, and using groups is probably the safest.
 
 - Bootconfig memory managament updates.
 
 - Bootconfig clean up to have the tools directory be less dependent on
   changes in the kernel tree.
 
 - Allow perf to be traced by function tracer.
 
 - Rewrite of function graph tracer to be a callback from the function tracer
   instead of having its own trampoline (this change will happen on an arch
   by arch basis, and currently only x86_64 implements it).
 
 - Allow multiple direct trampolines (bpf hooks to functions) be batched
   together in one synchronization.
 
 - Allow histogram triggers to add variables that can perform calculations
   against the event's fields.
 
 - Use the linker to determine architecture callbacks from the ftrace
   trampoline to allow for proper parameter prototypes and prevent warnings
   from the compiler.
 
 - Extend histogram triggers to key off of variables.
 
 - Have trace recursion use bit magic to determine preempt context over if
   branches.
 
 - Have trace recursion disable preemption as all use cases do anyway.
 
 - Added testing for verification of tracing utilities.
 
 - Various small clean ups and fixes.
