Subject: [PATCH 2/2] KVM: riscv: selftests: Add common supported test cases

From: Quan Zhou <zhouquan@...as.ac.cn>

Some common KVM test cases are supported on riscv now as following:

    access_tracking_perf_test
    demand_paging_test
    dirty_log_perf_test
    dirty_log_test
    guest_print_test
    kvm_binary_stats_test
    kvm_create_max_vcpus
    kvm_page_table_test
    memslot_modification_stress_test
    memslot_perf_test
    rseq_test
    set_memory_region_test

Add missing headers for tests and fix RISCV_FENCE redefinition
in `rseq-riscv.h` by using the existing macro from <asm/fence.h>.
