Hi Joe,

Thanks, I was using patch command to apply the patches and using git am
helped. Sorry for the noise. The test cases passes now, without the issue
I previously reported:

[...]
# TEST: livepatch interaction with ftrace_enabled sysctl ... ok
ok 4 selftests: livepatch: test-ftrace.sh

Long story is that the patch command version installed on the test machine
doesn't understand new file mode permission from the git diff, updating
the patch version creates the patch with 755 mode.
