charset="UTF-8" Use kvm_is_vcpu_creation_in_progress() instead of an open-coded equivalent during AIA initialization. Unlike similar vGIC code in arm64, the relevant RISC-V code runs under kvm->lock, i.e. can use the standard API without hitting lockdep false positive. No functional change intended.
