Xiao Guangrong e5691a81e8 KVM: MMU: clear write-flooding on the fast path of tracked page
If the page fault is caused by write access on write tracked page, the

flooding for the page structure current vcpu is using

Fix it by locklessly waking shadow page table to clear write flooding
on the shadow page structure out of mmu-lock. So that we change the
count to atomic_t
