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
  x86_64-linux-gnu-ld: arch/x86/boot/compressed/head_64.o: warning: relocation in read-only section `.head.text'
  x86_64-linux-gnu-ld: warning: creating DT_TEXTREL in a PIE

This started happening after 984b78c4ecea49b0b4b5729a502b689a623fde27 ("x86/speculation: Fix RSB filling with CONFIG_RETPOLINE=n").
