get_random_nonce style functions seem to be patched out due to jump label optimizations

introduced by:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a48e42920ff38bc90bbf75143fff4555723d4540

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/include/linux/net.h?id=3d4405226d27b3a215e4d03cfa51f536244e5de7

Only 3.13 and 3.14 affected apparently, so neither SLE12 nor openSUSE affected.

This seems to be 3.13+ material so nothing to be done for TD branches
