And the v1 patches fix some coverity errors and loongarch_cpu_class_by_name function for LoongArch virt machine. 1. Use MAKE_64BIT_MASK(shift, len) to replace 'xxx << shift'. 2. Use ARRAY_SIZE(arrqy) to get the array size. 3. Add the assertion that 'cpu_model' resolve to a class of the appropriate type.
