The user pages are generally allocated using GFP_USER or GFP_HIGHMEM
flags. The linux kernel treats GFP_USER and GFP_KERNEL as same. So,
there is no way you can tell whether a physical page belongs to user
process or not using physical frame number.

Hi All,
Does anybody know if there is a way in Linux Kernel to find whether a
physical page is a user page or it is kernel page. A kernel page is
only accessed by kernel and it doesn't belong to any user process.
Thanks,
Piyus
