Merge branch 'kvm-arm64/sea-user' into kvmarm/next
* kvm-arm64/sea-user:
: Userspace handling of SEAs, courtesy of Jiaqi Yan
:
: Add support for processing external aborts in userspace in situations
: where the host has failed to do so, allowing the VMM to potentially
: reinject an external abort into the VM.
Documentation: kvm: new UAPI for handling SEA
KVM: selftests: Test for KVM_EXIT_ARM_SEA
KVM: arm64: VM exit to userspace to handle SEA
