Merge branch kvm-arm64/6.6/misc into kvmarm-master/next
* kvm-arm64/6.6/misc:
: .
: Misc KVM/arm64 updates for 6.6:
:
: - Don't unnecessary align non-stack allocations in the EL2 VA space
:
: - Drop HCR_VIRT_EXCP_MASK, which was never used...
:
: - Don't use smp_processor_id() in kvm_arch_vcpu_load(),
: but the cpu parameter instead
:
: - Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
:
: - Remove prototypes without implementations
: .
KVM: arm64: Remove size-order align in the nVHE hyp private VA range
KVM: arm64: Remove unused declarations
KVM: arm64: Remove redundant kvm_set_pfn_accessed() from user_mem_abort()
KVM: arm64: Drop HCR_VIRT_EXCP_MASK
KVM: arm64: Use the known cpu id instead of smp_processor_id()
