Because restore_registers() is page-aligned, the assembler inexplicably adds an unreachable jump from after the end of the previous function to the beginning of restore_registers(). That confuses objtool, understandably. It also creates significant text fragmentation. As a result, most of the object file is wasted text (nops). Move restore_registers() to the beginning of the file to both prevent the text fragmentation and avoid the dead jump instruction. $ size /tmp/hibernate_asm_64.before.o /tmp/hibernate_asm_64.after.o text data bss dec hex filename 4415 0 0 4415 113f /tmp/hibernate_asm_64.before.o 524 0 0 524 20c /tmp/hibernate_asm_64.after.o Cc: "Rafael J.
