Comment 4 for bug 1751202

Looks like the change to how /proc/kallsyms displays addresses was introduced in:

    Make %p print '(null)' for NULL pointers

Upstream fixed it in 3a129cc2151425e5aeb69aeb25fbc994ec738137 but was not originally submitted to linux-stable (that has been rectified).

It could be worked around in the qrt script, but I'm not convinced that's the right thing to do here.

It should be noted that the behavior that the script is testing for, kernel addresses in /proc/kallsyms not being visible to unprivileged processes, is correct here. So there's no security impact from this, and it should not block promoting kernels, from the security team's perspective.
