I'm not saying whether this breaks some logic or not.

rmap_printk("rmap_write_protect: spte %p %llx\n", sptep, *sptep);
helps developers by saying "rmap_write_protect() protected ...."

For another function, the message should be "another_func_name: spte ..."
But OK, I won't argue about this anymore.

We can change the debug message later if needed.

Thanks,
