    It might be possible to rework the memaccess code to take advantage
    of all the parameters. I will defer this to the memaccess folks.

Could you elaborate on what you mean?


Never mind, I see it. Yes, doing __p2m_get_mem_access and then
p2m_get_entry later duplicates work. I would suggest just replacing
__p2m_get_mem_access with a single call to p2m_get_entry to get both
the type and the mem_access setting on the page in a single run.

I am not planning to clean-up the memaccess code. Feel free to send a follow-up patch for that.
