It's immediately after/before the call to the VDSO function itself.
Next I'll try to instrument the VDSO to get closer to that syscall.

I produced those reg dumps by hooking the page fault handler in the
kernel to print them and then disabling aslr and sticking a
`*(volatile int *)0 = 0;` in the code. Pretty gnarly.
