[PATCH 3.19 035/123] drm/radeon: Changing number of compute pipe lines

[Greg Kroah-Hartman]

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

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

From: Ben Goz <ben.goz@xxxxxxx>

commit e405ca3a1bf166f741506c07c2a277b5d48af8f7 upstream.

The current CP firmware can handle Usermode Queues only on MEC1.
To reflect this firmware change, this commit reduces number of compute pipelines
to 4 - 1, from 8 - 1 (the first pipeline is allocated for kgd).
