Just like on amd64. Instead of keeping a bitmap of which cpus a pmap
is active on, save a curpmap pointer in cpu_info. This lets us simplify
a few things and do lazy context switching from a user process to a
kernel thread. There's a new IPI introduced for forcing a cr3 reload
when we're tearing down a dead pmap.
