Running objtool --vmlinux --duplicate on vmlinux.o produces a few warnings about indirect jumps with retpoline: vmlinux.o: warning: objtool: wakeup_long64()+0x61: indirect jump found in RETPOLINE build ... This change adds ANNOTATE_RETPOLINE_SAFE annotations to the jumps in assembly code to stop the warnings. Signed-off-by: Sami Tolvanen <samitolvanen@google.com>
