KVM: LoongArch: selftests: Add system registers save/restore on exception2025-11-27T03:00:18ZBibo Maomaobibo@loongson.cn2025-11-27T03:00:18Zurn:sha1:985a96983bedf04fa61315e68806f3468450c8a1
When system returns from exception with ertn instruction, PC comes from
LOONGARCH_CSR_ERA, and CSR.CRMD comes LOONGARCH_CSR_PRMD.
Here save CSR register CSR.ERA and CSR.PRMD into stack, and then restore
them from stack. So it can be modified by exception handlers in future.
