Turned off DMA prefetch for the P600 on systems which may present
discontiguous memory.

What do you mean by "discontiguous memory"? CONFIG_DISCONTIGMEM?

What is the actual problem which is being fixed here?

+#if defined CONFIG_IA64 || if defined CONFIG_X86_64

hm, does that work?

I'll change it to

#if defined(CONFIG_IA64) || defined(CONFIG_X86_64)
