SRU Justification
[Impact]
There seems to have been a typo in Commit 85bf17b28f97
("recordmcount.pl: look for jgnop instruction as well as bcrl on s390")
that causes errors in finding mcount locations. This seems to cause problems
with ftrace initialization leading to not being able to use ftrace
functions.
[Fix]
Fix the typo by changing it to the correct instruction.
[Test Case]
Ftrace files in /sys/kernel/debug/tracing should be able to be read from and
written to with normal functionality. Ftrace selftests should now pass.
[Where things could go wrong]
Its a simple typo fix so none really.
