Some driver(e.g. bnx2) do the following to enable MSI-X:
1. Mask all vectors.
2. Write the msg data and address.

4. Unmask all the vectors.
For this, check per-vector mask bit before enable MSI-X would cause device

into diffrent physical page.
this function is working by removing oldpage from the rmap and calling
put_page on it, and by setting the pte to point into newpage and by

this macro allow setting the pte in the shadow page tables directly
instead of flushing the shadow page table entry and then get vmexit in
