lib/libc/arch/amd64/sys: Ovfork.S
Log message:
Make two corrections to the vfork(2) stub:
* with IBT, it can't return via an indirect jump as that would
require the *caller* to have an endbr64
* to support a potential vmspace-sharing implementation, keep the
retguard value in an arg register across the underlying syscall
