+Subject: [PATCH] gstreamer/gst/gstconfig.h.in: Add support for LoongArch
+
+While current and future LoongArch machines that are supposed to run
+GStreamer all support unaligned accesses, there might be future
+lower-end cores (e.g. the embedded product line) without such support,
+and we may not want to penalize these use cases.
+
+So, mark LoongArch as not supporting unaligned accesses for now, and
+hope the compilers do a good job optimizing them. We can always flip
+switch later.
