Wonderful, this is all looking quite sane now.
drivers/char/Kconfig | 2
drivers/input/serio/i8042.h | 2
drivers/net/Kconfig | 2
drivers/scsi/Kconfig | 2
drivers/serial/Kconfig | 8
drivers/watchdog/Kconfig | 2
fs/partitions/Kconfig | 2
As just discussed on IRC this all should go via the respective maintainers
or where none is available via akpm + lkml.

I've always been wondering if the even the IP22 segment was correct at
all. Afair nobody ever had (E)ISA DMA working on Indigo 2 so that code
is a shot into the dark. Of course for now it's the sanest thing to
assume that IP28 is the same as the "classic" Indigo 2.
