Wire up the system call tracepoints with Tasks Trace RCU to allow
the ftrace, perf, and eBPF tracers to handle page faults.
This series does the initial wire-up allowing tracers to handle page
faults, but leaves out the actual handling of said page faults as future
work.
This series is based on kernel v6.5.5.
Feedback is welcome!
Thanks,
Mathieu
