[PATCH] kcalloc(): INT_MAX -> ULONG_MAX
Since size_t has the same size as a long on all architectures, it's enough
for overflow checks to check against ULONG_MAX.
This change could allow a compiler better optimization (especially in the
n=1 case).
The practical effect seems to be positive, but quite small:
