o Switch to ITANIUM2 has the cpu. This has absolutely no effect
on the code, but makes for a better example.
o Drop COMPAT_FREEBSD6. We're tier 2, so you're supposed to run
8-stable or newer.
o Add PREEMPTION. It works now.
o Remove HWPMC_HOOKS. We don't have support for hwpmc yet.
o Add a bunch of new devices: atapist, hptiop, amr, ips, twa, igb,
ixgbe, ae, age, alc, ale, bce, bfe, et, jme, msk, nge, sk, ste,
stge, tx, vge, axe, rue, udav, fwip, and all USB serial.
o Remove "legacy" devices: le, vx, dc, pcn, rl, sis.
Make sure to the module list is a superset of what goes into GENERIC.
