KVM: PPC: Interpret SR registers on demand
Right now we're examining the contents of Book3s_32's segment registers when the register is written and put the interpreted contents into a struct. There are two reasons this is bad. For starters, the struct has worse real-time performance, as it occupies more ram. But the more important part is that with segment registers being interpreted from their raw values, we can put them in the shared page, allowing guests to mess with them directly. This patch makes the internal representation of SRs be u32s. Signed-off-by: Alexander Graf <agraf@suse.de>
