I'm in the process of merging this patch, but when I build a
"generic" kernel (with CONFIG_NUMA=y and CONFIG_DISCONTIGMEM=y),
I get many new warnings:

/home/helgaas/bk/testing/include/asm/mmzone.h:62:21: warning: "virt_to_page" redefined
/home/helgaas/bk/testing/include/asm/page.h:57:1: warning: this is the location of the previous definition
/home/helgaas/bk/testing/include/asm/mmzone.h:71:21: warning: "page_to_phys" redefined
/home/helgaas/bk/testing/include/asm/page.h:58:1: warning: this is the location of the previous definition
/home/helgaas/bk/testing/include/linux/mmzone.h:229:21: warning: "numa_node_id" redefined
/home/helgaas/bk/testing/include/asm/processor.h:206:1: warning: this is the location of the previous definition

Could you look into these and send a new patch to correct them?
Also, the resulting kernel doesn't boot (it MCAs) on HP rx2600
and zx2000.  I'll look into it in my spare time, but you can
probably do so more efficiently.

A small patch that applies on top of the previous patch would be
easiest.
