I'll fix all warnings. And about problems on HP machines, I guess the reason is that the current CONFIG_NUMA kernel doesn't work right on a system which needs the VIRTUAL_MEM_MAP function. I thought that the CONFIG_NUMA kernel doesn't have to work on such the systems, I mean you can make a kernel with just turning off CONFIG_NUMA at config. However, it would better if CONFIG_NUMA kernel works on all types of machines. So I'll try to find out a solution for this issue.
