* kvm-arm64/pkvm-vcpu-state: (25 commits) : . : Large drop of pKVM patches from Will Deacon and co, adding : a private vm/vcpu state at EL2, managed independently from : the EL1 state. From the cover letter: : : "This is version six of the pKVM EL2 state series, extending the pKVM : hypervisor code so that it can dynamically instantiate and manage VM : data structures without the host being able to access them directly. : These structures consist of a hyp VM, a set of hyp vCPUs and the stage-2 : page-table for the MMU. The pages used to hold the hypervisor structures : are returned to the host when the VM is destroyed." : . KVM: arm64: Use the pKVM hyp vCPU structure in handle___kvm_vcpu_run() KVM: arm64: Don't unnecessarily map host kernel sections at EL2 KVM: arm64: Explicitly map 'kvm_vgic_global_state' at EL2 KVM: arm64: Maintain a copy of 'kvm_arm_vmid_bits' at EL2 KVM: arm64: Unmap 'kvm_arm_hyp_percpu_base' from the host KVM: arm64: Return guest memory from EL2 via dedicated teardown memcache KVM: arm64: Instantiate guest stage-2 page-tables at EL2 KVM: arm64: Consolidate stage-2 initialisation into a single function KVM: arm64: Add generic hyp_memcache helpers KVM: arm64: Provide I-cache invalidation by virtual address at EL2 KVM: arm64: Initialise hypervisor copies of host symbols unconditionally KVM: arm64: Add per-cpu fixmap infrastructure at EL2 KVM: arm64: Instantiate pKVM hypervisor VM and vCPU structures from EL1 KVM: arm64: Add infrastructure to create and track pKVM instances at EL2 KVM: arm64: Rename 'host_kvm' to 'host_mmu' KVM: arm64: Add hyp_spinlock_t static initializer KVM: arm64: Include asm/kvm_mmu.h in nvhe/mem_protect.h KVM: arm64: Add helpers to pin memory shared with the hypervisor at EL2 KVM: arm64: Prevent the donation of no-map pages KVM: arm64: Implement do_donate() helper for donating memory ...
