This patch fixes the regression noted here:

Removing these devices (or any other plugged directly into the maple
ports) is a quick way to destroy your Dreamcast:

This patch fixes the DMA cascade by masking the correct bits.

Could someone here help settle this argument?
I have written a driver (for the CD Rom on the Sega Dreamcast). I have
marked various initialisation functions - including probe() and the
functions that it, and only it, calls, as __init.
Other developers tell me I should mark them as __devinit.
How
the issue of
__init versus __devinit - see http://lkml.org/lkml/2007/12/23/130 but
I think otherwise it has dealt with most people's suggestions. The one
exception is that Jens suggested using sector_div, though I found that
did not work.

and I am hitting what looks like some sort of race in
kernel/irq/manage.c. Can anybody point me in the right direction or is
