Subject: [PATCH] ver_linux: proc-modules.patch

The current implementation used a combination of both 'cat' and 'sed'
to generate an unsorted list of kernel modules separated by while space.

The proposed implementation uses 'sort' and 'sed' to generate a sort
list of kernel modules separated by while space.

Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2
