I don't really know what's happening at the low-level here in this patch, but
I've done some blind testing here's what I learned: the system wakes up from
suspend if I comment the following lines from the patch:

                 * hw_ssb_recalculate(true);
                 * amd64_syscall_ret_flush_l1d_recalc();
                 * x86_rngds_mitg_recalculate(true);
                if (vmm_resume_p != NULL)

If I uncomment the next line (hw_ssb_recalculate(true)) the laptop won't
wakeup.  But as I said, I've no idea why, this was just blind testing.
