+Subject: [PATCH] x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32
+
+Starting from binutils commit bd7ab16b4537788ad53521c45469a1bdae84ad4a:
+
+https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=bd7ab16b4537788ad53521c45469a1bdae84ad4a
+
+x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
+32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as
+R_X86_64_PC32.
