    kernel - Remove B_MALLOC
    
    * Remove B_MALLOC buffer support.  All primary buffer cache buffer
      operations should now use pages.  B_VMIO is required for all
      vnode-centric operations like allocbuf(), but does not have to be set
      for nominal I/O.
    
    * Remove vm_hold_load_pages() and vm_hold_free_pages().  This code was
      used to support mapping ad-hoc data buffers into buf structures, but
      the only remaining use case in the CAM periph code can just use
      getpbuf_mem() instead.  So this code is no longer used.
