3.6.11.9-rc1 stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Deucher <alexander.deuc...@amd.com> [ Upstream commit 42a21826dc54583cdb79cc8477732e911ac9c376 ] The ProcessAuxChannel table on some rv635 boards assumes the divmul members are initialized to 0 otherwise we get an invalid fb offset since it has a bad mask set when setting the fb base. While here initialize all the atom interpretor elements to 0.
