Currently PTRACE_SINGLESTEP after syscall_exit stop is not consistent
across different machines, and we have different problems depending
on arch/.
As Roland suggests, we should move the arch-dependent logic into the
tracehook_report_syscall_exit() and unify/fix the behaviour.
Oleg.
At least 4-5/5 should be CC'd to the x86 maintainers too.
At least 1/5 should perhaps go to linux-arch to alert other
arch maintainers that implement user_enable_single_step()
to add user_single_step_siginfo() for their arch too.
Thanks,
Roland
