I think I have cleared the issue regarding the reverse mapping.
I missed the fact, that the write permission is associated with the PTE.
I thought that it was associated only with the kernel structures
maintaining the physical page-frame.
But I want to confirm whether a shadowed guest page refers to "the guest
PT page that has a corresponding shadow PT page. And the corresponding
shadow PT page is called the shadow of the former. Am I right ?
Thanks and regards
Sukanto
