... snip ...

at this point, i'd be happier to leave the appropriate patches in the
hands of those who have a better handle on this. as i posted earlier,
there's only two examples of this in the entire tree:

drivers/scsi/aic7xxx_old.c: aic_dev = kmalloc(sizeof(struct aic_dev_data), GFP_ATOMIC | GFP_KERNEL);
drivers/message/i2o/device.c: resblk = kmalloc(buflen + 8, GFP_KERNEL | GFP_ATOMIC);

it's all yours.
