Even I do not realy use any ISA code of ALSA on my iPAQ I need it for compilation. As I build ALSA as modules, the dma_spin_lock symbol is missing.

I have seen both definitions of dma_spin_lock (in kernel/dma.c and arch/arm/kernel/dma.c) same as EXPORT_SYMBOL in kernel/ksyms.c, but I think, exporting it in arch/arm/kernel/dma.c should be better then making confusion in kernel/ksyms.c

2Russel: If you don't think this is good solution, we should discuss this in linux-arm-kernel mailing list
