basically, mcmodel defaults to small in most cases, which means
32b data relocations. medium bumps single-object addressability
up to 64b. neither of these affect the basic addressing model
(int=32b, long=64b, pointer=64).

not a kernel issue, but rather the width of address calculations
for a single addressable object (as decided by the compiler.)
