Here is the new version. I haven't introduced any warnings in this round, but I did in my previous round. I cleaned those now. I also added paca size display to dump_offset_table().

BTW: crash is broken for CONFIG_SPARSEMEM (which seems to be default for ppc64). I had to hack it every time to make crash work on ppc64. Do you want to include temporary hack to make crash work till it gets fixed for real. (with the hack most commands work, but some memory related commands show wrong data).
