+Subject: [PATCH] xtensa: fix signedness of gas relocations
+
+Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
+offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
+substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
+8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
+directive. Revert this part and add test.
