Darren Hart - Jan. 21, 2014, 10:39 p.m.
Core2 has both a 32b and a 64b variant. Currently, core2 implies 32b,
while core2_64 is the 64b version. This implicit 32b mode will become
confusing in later architectures, such as corei7, where it would be
natural for people to assume "corei7" meant 64 bit.

Rather than carrying forward an implicit 32b mode and rather than
changing the naming scheme part way through the architecture hiearchy,
make the 32b and 64b variant explicit in the tune name by changing core2
to core2_32.
