Juergen Gross c6eef36436 objtool/x86: allow syscall instruction ... commit dda014ba59 upstream. The syscall instruction is used in Xen PV mode for doing hypercalls. Allow syscall to be used in the kernel in case it is tagged with an unwind hint for objtool. This is part of XSA-466 / CVE-2024-53241.
