+Subject: [PATCH] fix: gallivm: limit usage of LLVMContextSetOpaquePointers()
+ to LLVM 15
+
+LLVMContextSetOpaquePointers() was a temporary workaround offered to
+allow transitioning to opaque pointers. Mesa is ready for this now with
+recent versions of LLVM (16+). Therefore we limit the workaround of
+using LLVMContextSetOpaquePointers() to LLVM 15 now, that this C
+interface was removed in LLVM 17.

+Subject: [PATCH] gallium: Fix build with llvm 17
+
+These headers are not available for C files in llvm 17+
+and they seem to be not needed to compile after all with llvm 17
+so add conditions to exclude them for llvm >= 17
