Something may change here: when level PT_PAGE_TABLE_LEVEL, this loop

This may be incorrect.
On second thoughts, this seems to be no problem.

We will use this in the following patch to implement another function
which needs to write protect pages using the rmap information.
Note that there is a small change in debug printing for large pages:
we do not differentiate them from others to avoid duplicating code.
