From ec55fd5868855f6e40beb7b1a78fc2defc0c219b Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/gf100-/gr: implement the proper SetShaderExceptions
method
We have another version of it implemented in SW, however, that version
isn't serialised with normal PGRAPH operation and can possibly clobber
the enables for another context.
This is the same method that's implemented by the NVIDIA binary driver.
