I am a bit puzzled how this differs from the pkey's that other architectures are implementing to achieve a similar result. I am a bit mystified why you don't store the tag in a vma instead of inventing a new way to store data on page out. Can you please use force_sig_fault to send these signals instead of force_sig_info. Emperically I have found that it is very error prone to generate siginfo's by hand, especially on code paths where several different si_codes may apply. So it helps to go through a helper function to ensure the fiddly bits are all correct. AKA the unused bits all need to be set to zero before struct siginfo is copied to userspace.
