If this is off-topic, my apologies.
I am unable to build ALSA for 2.5.7 on i386. The problem is that
the ALSA code uses a function virt_to_bus( ). This is #defined in
asm/io.h as virt_to_bus_not_defined_use_pci_map( ). So there is
an unresolved external.
The correct replacement of virt_to_bus( ) to pci_map_*( ) is not
obvious to a newbie from a look at pci.h.
Am I missing something? I think I must be. So , is there
a kernel config option that needs to be set/unset, or is there
a patch I should get?
BTW I tried building 2.5.8, but that failed spectacularly in other
areas not related to ALSA... Hmmmm, I've never had kernel build
problems before, I must be regressing!
thanks

Have a look at the DMA-Mapping.txt documentation file. Its not a trivial
replacement but its maybe one to have a go at.

is include/asm correctly symlinked to asm-i386?
all ALSA drivers (except for rme9652-mem and ppc ones) don't use
virt_to_bus() any more.
