Merge tag 'x86-entry-2023-10-28' of git://git.kernel.org/pub/scm/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
