Hg history: show all the changesets
Hg heads: show current head of the hg tree

I think normally elilo will place parameters, initrd, etc. in higher end
of physical memory, and it's unlikely to map all memories by one TR.
Actually the alt dtlb miss fault is wanted for Xen to access all the
physical memories. BTW, can you check whether 0x617ef90010 is legal
address in a memory bank on your box?
