Subject: [PATCH v2 3/6] perf kvm: Wire up e_machine
Pass the e_machine to the kvm functions so that they aren't just wired
to EM_HOST. In the case of a session move some setup until the session
is created. As the session isn't fully running the default EM_HOST is
returned as no e_machine can be found in a running machine. This is,
however, some marginal progress to cross platform support.
