--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Fixed in commit 07cecda.
It appears that the arm kernel's syscall_get_nr() function is designed to only
be used with ftrace syscall tracing. So, on arm, we'll use our own function.
With this patch, the number of syscall/nd_syscall passes almost doubles:
====
# of expected passes 129
# of unexpected failures 137
