Anup Patel 2a673aca82 RISC-V: KVM: Don't treat SBI HFENCE calls as NOPs ... [ Upstream commit 2e7be16299 ] The SBI specification clearly states that SBI HFENCE calls should return SBI_ERR_NOT_SUPPORTED when one of the target hart doesn’t support hypervisor extension (aka nested virtualization in-case of KVM RISC-V).
