I grepped through include/asm-* and found: #if defined(CONFIG_FLATMEM) #ifndef ARCH_PFN_OFFSET #define ARCH_PFN_OFFSET (0UL) #endif in include/asm-generic/memory_model.h. So I'm still confident, that this works on all architectures. It's tested on MIPS. Thomas. -- Crap can work. Given enough thrust pigs will fly, but it's not necessary a good idea.
