3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 9f050c7f9738ffa746c63415136645ad231b1348 upstream.
Print the supported functions mask in addition to
the version. This is useful in debugging PX
problems since we can see what functions are available.
