Hi, Changes since v6 [1]: - Rebase on 5.15-rc4 - Include Marc's updated 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 [2]. This series is based on 5.15-rc4. You can find the applied series here [3].
