+Subject: [PATCH 04/52] [LOCAL]: Fix relaxation of assembler resolved
+ references,Fixup debug_loc sections after linker relaxation Adds a new
+ reloctype R_MICROBLAZE_32_NONE, used for passing reloc info from the
+ assembler to the linker when the linker manages to fully resolve a local
+ symbol reference.
+This is a workaround for design flaws in the assembler to
+linker interface with regards to linker relaxation.

-Subject: [PATCH 06/40] microblaze: Fixup debug_loc sections after linker
- relaxation
-Adds a new reloctype R_MICROBLAZE_32_NONE, used for passing
-reloc info from the assembler to the linker when the linker
-manages to fully resolve a local symbol reference.
-This is a workaround for design flaws in the assembler to
-linker interface with regards to linker relaxation.
