Paolo, Radim, Here's the bulk of KVM/arm updates for 5.5. On the menu, two new features: - Stolen time is finally exposed to guests. Yay! - We can report (and potentially emulate) instructions that KVM cannot handle in kernel space to userspace. Yay again! Apart from that, a fairly mundane bag of perf optimization, cleanup and bug fixes. Note that this series is based on a shared branch with the arm64 tree, avoiding a potential delicate merge. Please pull, M.
