Looking at the snippet
...
      if (!inclusive_cache)
        {
          if (threads_l2 > 0)
            core /= threads_l2;
          shared += core;
        }
...
with both "core" and "shared" being initialized with the return value of
"handle_intel":

in case of return value of 0:
core = 0/xxx  = 0
shared = 0+0  = 0

in case of return value -1
core = -1/xxx = yyy
shared = -1 + -1 = -2

because of the later use of these variables their value is indifferent
as long it is below or equal to zero. 
So "0" as return value of "handle_intel" seems ok to me.
