Author: coypu <coypu@sdf.org>
Date: Mon Mar 4 12:24:37 2019 +0200

Make GCC happier about prototype, include right header for __HAVE_ATOMIC64_OPS

commit 93c2f416aa316cc3d0665661c9f927f6949cdd37
Author: coypu <coypu@sdf.org>
Date: Mon Mar 4 12:16:56 2019 +0200

Make the u_atomic.c fallback locked 64bit atomics more suited

for the netbsd case: we are using __GNUC__ compilers, but without
libatomic. so we are emitting the __GNUC__ names.

Use __HAVE_ATOMIC64_OPS which is the netbsd name for this condition
(we don't run configure)

Remove unused padding to struct.

The extra space is in the flexible array member at the end of
struct drm_i915_query_topology_info.

Clang dislikes having an extra member to the struct after the flexible
array member.

Author: Maya Rashish <maya@NetBSD.org>
Date: Wed Feb 6 13:07:55 2019 +0200

Apply patches from pkgsrc mesa to avoid atexit on a library.

This isn't safe to do on netbsd and results in segfaults on
program exit.

radeon picture_type is h264 and the enums match, cast to avoid

clang warning (we use -Werror)
