KVM: PPC: Book3S HV: Simplify dynamic micro-threading code
Since commit b009031f74da ("KVM: PPC: Book3S HV: Take out virtual core piggybacking code", 2016-09-15), we only have at most one vcore per subcore. Previously, the fact that there might be more than one vcore per subcore meant that we had the notion of a "master vcore", which was the vcore that controlled thread 0 of the subcore. We also needed a list per subcore in the core_info struct to record which vcores belonged to each subcore. Now that there can only be one vcore in the subcore, we can replace the list with a simple pointer and get rid of the notion of the master vcore (and in fact treat every vcore as a master vcore). We can also get rid of the subcore_vm[] field in the core_info struct since it is never read. Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
