Alexander Graf 97c4cfbe89 KVM: PPC: Enable lightweight exits again ... The PowerPC C ABI defines that registers r14-r31 need to be preserved across function calls. Since our exit handler is written in C, we can make use of that and don't need to reload r14-r31 on every entry/exit cycle. This technique is also used in the BookE code and is called "lightweight exits" there. To follow the tradition, it's called the same in Book3S. So far this optimization was disabled though, as the code didn't do what it was expected to do, but failed to work. This patch fixes and enables lightweight exits again.
