kmem_alloc: NULL ptr (name=unknown) - is it a serious problem?

[Jun Sun <jsun@mvista.com>]

I found a couple of these annoying messages at the beginning of kernel
startup.  It seems that some subsystems are requesting regions
(request_region()) before kernel even initialize its memory.

It appears to me this reservation is just for mutual exclusive access to
some memory region.  Since I have a static system (no PnP and hot swap
etc), so I can safely ignore them. 

Does that make sense?

What is the right to avoid these warnings?
