Description
The code for nfs root mounts does not use kmalloc-ed space for some vars, while
some KKASSERTs in the mentioned files only check for the supplied pointers if
they were kmalloc-ed or not.
The attached patch adds a check if the supplied pointers are not in user stack
(if they are in kernel stack) ... since kmalloc-ed space also resides in the
addresses not in user stack, maybe kva_p should be removed (is it used
anywhere else?)?

Hi,
Indeed, kva_p() is only used in uipc_msg.c and uipc_socket.c
Matt, what do you think about the attached patch?
Cheers,
Antonio Huete
