+Subject: [PATCH] mips: Fix build on MIPS64 with n32 ABI
+
+The build on MIPS64 with n32 ABI was broken for a few reasons.
+
+- The _movi_d_w() functions had a different prototype in jit_mips-fpu.c
+  than in lightning.c;
+- The movi_d_w() was still provided by lightning.c even though
+  jit_mips-fpu.c provides its own version;
+- The "ww" opcodes were allowed, which was probably not meant to happen.
+
+Fixes a build issue reported by Buildroot:
+http://autobuild.buildroot.net/results/27123bf0ddc84599bceb02ac987327817d498659/
