I'm not entirely sure what your problem is; I'm going to guess that the
problem is actually with "when writing in shared mem, paging ooopses
outcome" -- did you use memcpy, or direct assignment (=) or
copy_to_user?

Unless you used copy_to_user (or the function that is similar, but
optimized for 1, 2, or 4 bytes, whose name I can never recall) then I'd
wager this is the problem, and not the semaphore.

Good luck
