Upstream commit
66cc69e34e86a "Fix: module signature vs tracepoints: add
new TAINT_UNSIGNED_MODULE" fixed an issue where the kernel was
considering unsigned modules as tainting the kernel in the same way as a
force-loaded modules, which was causing the tracepoints within those
modules to be hidden.
This fix was merged in kernel 3.15, so there is no use in applying this
work-around starting from that kernel.
This removes a dependency on kallsyms_lookup_name() for the symbol
"tracepoint_module_notify".
