+Subject: mesa: Allow query of MAX_SAMPLES with EXT_framebuffer_multisample
+
+Previously queries of MAX_SAMPLES were only allowed with
+ARB_framebuffer_object, but EXT_framebuffer_multisample also enables
+this query.  This seems to only effect the i915.  All other drivers
+support both extensions or neither extension.
+
+This patch is based on a patch that Kenneth sent along with the report.
+
+NOTE: this is a candidate for the 7.9 branch.
