Hi, Changes since v5 [1]: - Rebase on 5.15-rc2 - Include Marc's early exception handlers in the series - Refactoring and fixes (Drew, Marc) This patch series adds support for restricting CPU features for protected VMs in KVM (pKVM). For more background, please refer to the previous series [1]. This series is based on 5.15-rc2. You can find the applied series here [2].
