Subject: [PATCH] mars: generic pre-patch for mars

Mostly introduces missing EXPORT_SYMBOL().
Should have exactly zero impact onto the kernel.

This is the generic version which exports all sys_*() system
calls. This should not introduce any additional maintenance pain
because that interfaces has to be stable anyway due to POSIX etc.
