Subject: [PATCH v6 4/4] KVM: selftests: Add test cases for LoongArch

From: Tianrui Zhao <zhaotianrui@...ngson.cn>

Some common KVM testcases are supported on LoongArch now as following:
	demand_paging_test
	dirty_log_perf_test
	dirty_log_test
	guest_print_test
	hardware_disable_test
	kvm_binary_stats_test
	kvm_create_max_vcpus
	kvm_page_table_test
	memslot_modification_stress_test
	memslot_perf_test
	set_memory_region_test
And other test cases are not supported by LoongArch such as rseq_test,
since it is not supported on LoongArch physical machine neither.
