Merge tag 'x86-entry-2023-10-28' of git://git./linux/kernel/git/tip/tip

Pull x86 entry updates from Ingo Molnar:

 - Make IA32_EMULATION boot time configurable with
   the new ia32_emulation=<bool> boot option

 - Clean up fast syscall return validation code: convert
   it to C and refactor the code

 - As part of this, optimize the canonical RIP test code
