kvm_vm_ioctl_get_dirty_log - get and clear the log of dirty pages in a slot : kvm instance : slot id and address to which we copy the log

We need to keep it in mind that VCPU threads can write to the bitmap concurrently. So, to avoid losing data, we keep the following order for each bit:

  1. Take a snapshot of the bit and clear it if needed.
  2. Write protect the corresponding page.
  3. Flush TLB's if needed.
  4. Copy the snapshot to the userspace.

Between 2 and 3, the guest may write to the page using the remaining TLB entry. This is not a problem because the page will be reported dirty at step 4 using the snapshot taken before and step 3 ensures that successive writes will be logged for the next call.
