I got the ramdisk stuff working. My latest problem is that the load of
misc/strplumb is failing and I can't work out what's wrong (no dependencies
and, apparently, no unresolved addresses).
One area that will require major work (but is working thanks to low activity)
is the allocation of page tables. On s390x page tables for levels 1-4 are 16K
in length and for level 0 it's 2K. At the moment I'm using a call to
page_create_va to get pages to build these tables. However, I cannot (or
page_create_va) cannot guarantee that I'll get contiguous pages. What I need to
do is create an allocation based on structures like memlist except instead of
containing address/size information it holds pfn/length information.
