These aren't effected by the patch. All the occurances of it inside the
kernel are explicitly written for the vdso/vsyscall functionality (which
needs it, since it's mapped into a userspace task, and you obviously
might be running a debugger on it.) The other hit in x86_64 is just a
discard section of the linker script.
