I did a *very* quick read through and didn't see anything egregious. I really
hope that someday we can deduplicate much of the ARM/RISC-V/LoongArch code, but
that's no reason to hold up getting selftests support merged.
kvm seltests for LoongArch originally comes from ARM64, especially ucall
and page table walk code. And LoongArch kvm actually benefits much from
open source code, we will deduplicate some ARM/RISC-V/LoongArch kvm
selftests code when LoongArch KVM is basically supported.
