Subject: [PATCH 3.11 126/131] drm/radeon: print the supported atpx function mask

3.11.10.6 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@....com>

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.
