    kvm: support using KVM_MEM_READONLY flag for regions

    

    For readonly memory regions and rom devices in romd_mode,

    we make use of the KVM_MEM_READONLY. A slot that uses

    KVM_MEM_READONLY can be read from and code can execute from the

    region, but writes will exit to qemu.

After reverting this commit, VM can boot normally.

Any information I should provide?
