xen: convert p2m to a 3 level tree

observed in the dump:

*pdpt =

Adding further debug statements showed that when trying to set up
pfn=0x26700 the returned mapping was invalid.
pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003)
pfn=0x26700 calling set_pte(0xc1fe7800, 0x3)
Although the last_pfn obtained from the startup info is 0x26700, which
should in turn not be hit, the additional 8MB which are added as extra
memory normally seem to be ok. This lead to looking into the initial
p2m tree construction, which uses the smaller value and assuming that
there is other code handling the extra memory.
When the p2m tree is set up, the leaves are directly pointed to the
array which the domain builder set up. But if the mapping is not on a
boundary that fits into one p2m page, this will result in the last leaf
being only partially valid. And as the invalid entries are not
initialized in that case, things go badly wrong.
I am trying to fix that by checking whether the current leaf is a
complete map and if not, allocate a completely new page and copy only
the valid pointers there. This may not be the most efficient or elegant
solution, but at least it seems to allow me booting DomUs with memory
assignments all over the range.

Newer versions of the System p firwmare send a partial RTAS error log in the

This means at machine check time we do not have enough information to
ascertain exactly what went on. Furthermore, I have found the RTAS error

them makes little sense. If we want to halt it would make more sense to do
