Vincent Chen 33e5b5746c KVM: RISC-V: Avoid spurious virtual interrupts after clearing hideleg CSR ... When the last VM is terminated, the host kernel will invoke function hardware_disable_nolock() on each CPU to disable the related virtualization functions. Here, RISC-V currently only clears hideleg CSR and hedeleg CSR. This behavior will cause the host kernel to receive spurious interrupts if hvip CSR has pending interrupts and the corresponding enable bits in vsie CSR are asserted. To avoid it, hvip CSR and vsie CSR must be cleared before clearing hideleg CSR.
