We are seeing a new warning on x86_64:

   /builds/linux/arch/x86/entry/entry_64.S: Assembler messages:
   /builds/linux/arch/x86/entry/entry_64.S:1756: Warning: no instruction mnemonic suffix given and no register operands; using default for `sysret'
   arch/x86/entry/entry_64.o: warning: objtool: .entry.text+0x151: unsupported intra-function call
