    Impact: crash on module insertion with CONFIG_DEBUG_VIRTUAL
    We would incorrectly BUG due to:
       VIRTUAL_BUG_ON(!is_vmalloc_addr(vmalloc_addr) &&
    ... because, at least on x86-64, is_module_address() doesn't do what
    it should.  This patch introduces is_vmalloc_or_module_addr(), which
    is what we really want anyway, and uses it instead.
