Re: Kernel Compile Fun

This has been discussed for at least 8 months (see the list archives),
and it was always asked why this is not corrected in the kernel trees. I
ask this again.

Some explanation: In arch/ppc/kernel/pmac_setup.c, the header file
<asm/dma.h> is included via <asm/scatterlist.h> via
"drivers/scsi/scsi.h", but only 
#if defined(CONFIG_SCSI) && defined(CONFIG_BLK_DEV_SD)
On the other hand, the variables ISA_DMA_THRESHOLD and so on are used
outside of any #if. This certainly looks like a bug.

You can fix this by inserting the line

#include <asm/dma.h>
into the file pmac_setup.c.

Thanks to Michael Fenske, who originally posted that message.  That fixed
the problem for me.

hope that works

I am having the worst possible time getting a newer kernel to compile.  I
received this error with both the stock 2.2.13 (and 2.2.14-pre18) kernel
