Hi, Guys:

I'm reading the QEMU code. I have a question haunting my mind for some time
about tb flushing due to MMU change. Generally, whenever the page table has
any change, we should flush the tb hash table. But I only see in the code that
when CR3 is changed, the tb_flush is called. What if the CR3 does not change,
but some level 2 page table in the memory change, should the tb also be flushed?
