PR_THP_DISABLE_EXCEPT_ADVISED extended PR_SET_THP_DISABLE to only provide
THPs when advised. IOW, it allows individual processes to opt-out of THP =
"always" into THP = "madvise", without affecting other workloads on the
system. The series has been merged in [1].

This patch documents the changes introduced due to the addition of
PR_THP_DISABLE_EXCEPT_ADVISED flag:
- PR_GET_THP_DISABLE returns a value whose bits indicate how THP-disable
  is configured for the calling thread (with or without
  PR_THP_DISABLE_EXCEPT_ADVISED).
- PR_SET_THP_DISABLE now uses arg3 to specify whether to disable THP
  completely for the process, or disable except madvise
  (PR_THP_DISABLE_EXCEPT_ADVISED).

I am not sure what the right time is to send the mandoc changes.
The patches have been merged into mm-new for more than 2 weeks.
We can still review it and I can resend if needed after the kernel release if that
is a more appropriate time?

Thanks!
