Merge tag 'trace-v7.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fix from Steven Rostedt:
- Fix CFI violation in probestub function
The probestub is a function to allow tprobes to hook to a tracepoint
to gain access to its parameters.
The function itself is only referenced by the tracepoint structure
which lives in the __tracepoint section. objtool explicitly ignores
that section and when processing functions in the kernel, if it
detects one that has no references it will seal it to have its ENDBR
stripped on boot up.
This means the probstub function will have its ENDBR stripped and if
a tprobe is attached to it with IBT enabled, it will go *boom*.

tracing: Fix CFI violation in probestub being called by tprobes
