+Subject: [PATCH] util: Update util/libdrm.h stubs to allow loader.c to compile
+ on MacOS.
+
+MacOS does not have the libdrm libraries so is missing xf86drm.h.
+util/libdrm.h already has a collection of stubs for systems that do not support the libraries.
+
+A compile on MacOS will fail with the source that uses newer drm functions and structures.
+Update adds in missing items that MacOS code needs to compile and run.
+New code is copied from the public repository: https://gitlab.freedesktop.org/mesa/drm/-/blob/main/xf86drm.h
