Josh Poimboeuf 1bcb58a099 objtool: Only print one warning per function ... When objtool discovers an issue, it's very common for it to flood the terminal with a lot of duplicate warnings. For example: warning: objtool: rtlwifi_rate_mapping()+0x2e7: frame pointer state mismatch warning: objtool: rtlwifi_rate_mapping()+0x2f3: frame pointer state mismatch warning: objtool: rtlwifi_rate_mapping()+0x2ff: frame pointer state mismatch warning: objtool: rtlwifi_rate_mapping()+0x30b: frame pointer state mismatch ... The first warning is usually all you need. Change it to only warn once per function.
