This series fix some coverity errors and loongarch_cpu_class_by_name function for LoongArch virt machine.
Only the loongarch_pch_pic patch(number 2/5) need to be reviewed in this v3 verison, and other patches have been reviewed. Changes for v3: 1. In loongarch_pch_pic file, We should not use 'unsigned long' type as argument when we use find_first_bit(), and we use ctz64() to replace find_first_bit() to fix this bug. 2. It is not standard to use '1ULL << irq' to generate a irq mask. So, we replace it with 'MAKE_64BIT_MASK(irq, 1)'. 3. Rewrite commit comments for op_helper patch(number 5/5). Changes for v2: 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. Changes for v1: 1. Fix coverity errors such as out-of-bounds, integer overflow, cond_at_most, etc. 2. Fix loongarch_cpu_class_by_name function. Please help review Thanks.
