* kvm-arm64/nv-xnx-haf: (22 commits)
: Support for FEAT_XNX and FEAT_HAF in nested
:
: Add support for a couple of MMU-related features that weren't
: implemented by KVM's software page table walk:
:
: - FEAT_XNX: Allows the hypervisor to describe execute permissions
: separately for EL0 and EL1
:
: - FEAT_HAF: Hardware update of the Access Flag, which in the context of
: nested means software walkers must also set the Access Flag.
:
: The series also adds some basic support for testing KVM's emulation of
: the AT instruction, including the implementation detail that AT sets the
: Access Flag in KVM.
KVM: arm64: at: Update AF on software walk only if VM has FEAT_HAFDBS
KVM: arm64: at: Use correct HA bit in TCR_EL2 when regime is EL2
KVM: arm64: Document KVM_PGTABLE_PROT_{UX,PX}
KVM: arm64: Fix spelling mistake "Unexpeced" -> "Unexpected"
KVM: arm64: Add break to default case in kvm_pgtable_stage2_pte_prot()
KVM: arm64: Add endian casting to kvm_swap_s[12]_desc()
KVM: arm64: Fix compilation when CONFIG_ARM64_USE_LSE_ATOMICS=n
KVM: arm64: selftests: Add test for AT emulation
KVM: arm64: nv: Expose hardware access flag management to NV guests
KVM: arm64: nv: Implement HW access flag management in stage-2 SW PTW
KVM: arm64: Implement HW access flag management in stage-1 SW PTW
KVM: arm64: Propagate PTW errors up to AT emulation
KVM: arm64: Add helper for swapping guest descriptor
KVM: arm64: nv: Use pgtable definitions in stage-2 walk
KVM: arm64: Handle endianness in read helper for emulated PTW
KVM: arm64: nv: Stop passing vCPU through void ptr in S2 PTW
KVM: arm64: Call helper for reading descriptors directly
KVM: arm64: nv: Advertise support for FEAT_XNX
KVM: arm64: Teach ptdump about FEAT_XNX permissions
KVM: arm64: nv: Forward FEAT_XNX permissions to the shadow stage-2
