From 898b25b202f3504335ae00055d7a2863bd93f2f8 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 22 Jun 2017 15:08:42 +1000 Subject: 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.
