None of the VM system is MP safe.

    kmalloc() and kfree() are MP safe, as is the OBJCACHE code
    (kern/kern_objcache.c).

    zalloc and friends are deprecated.  Only a few subsystems still use
    it and none of them are MP safe.  Most can easily be converted to
    using the objcache though the pmap code would probably need special
    attention.
