    This commit causes a build failure on arm64 defconfig:

    $ make -j$(nproc) ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- O=out defconfig Image.gz
    ...
    ../arch/arm64/kvm/../../../virt/kvm/kvm_main.c: In function '__kvm_map_gfn':
    ../arch/arm64/kvm/../../../virt/kvm/kvm_main.c:1763:9: error: implicit declaration of function 'memremap'; did you mean 'memset_p'? [-Werror=implicit-function-declaration]
    hva = memremap(pfn_to_hpa(pfn), PAGE_SIZE, MEMREMAP_WB);
    ^~~~~~~~
    memset_p

    memunmap(map->hva);
    ^~~~~~~~
    vm_munmap

    It seems that the <asm/io.h> include should probably be converted into
    <linux/io.h>.

    Cheers,
