+Subject: [PATCH] libavcodec: Remove dynamic relocs from h264idct_neon.S
+
+Some of the assembly functions e.g. ff_h264_idct_dc_add_neon
+has code like:
+ movrel x14, X(ff_h264_idct_add_neon)
+
+Linker cannot resolve them fully at link time and emits GOT
+relocations.
+Use explicit labels instead so that no dynamic relocations are
+needed at all.
+
+BUG=chromium:917919
+TEST=lld complains are fixed.
