Avi Kivity 86a5ba025d [PATCH] KVM: MMU: Page table write flood protection 
In fork() (or when we protect a page that is no longer a page table), we can
experience floods of writes to a page, which have to be emulated.  This is
expensive.

So, if we detect such a flood, zap the page so subsequent writes can proceed
natively.
