Hi Paolo, Here's the bulk of the KVM/arm64 updates for 5.19. Major features are guard pages for the EL2 stacks, save/restore of the guest-visible hypercall configuration and PSCI suspend support. Further details in the tag description. Note that this PR contains a shared branch with the arm64 tree containing the SME patches to resolve conflicts with the WFxT support branch. Please pull, M. The following changes since commit 672c0c5173427e6b3e2a9bbb7be51ceeec78093a: Linux 5.18-rc5 (2022-05-01 13:57:58 -0700) are available in the Git repository at:
