The purpose of this document is to record the differences between the
two linux directories and which firmware uses them.

1) linux-139 : linux kernel version 2.2.14 _WITHOUT_ the security patches.
               Used by TS firmware version 1.3.10 or older.

2) linux-1310 : linux kernel version 2.2.14 _WITH_ the security patches.
                Used by TS firmware version 1.3.11 or newer.

The main Makefile automatically creates a synbolic link "linux" to the
corresponding linux directory for the firmware version.
