Subject: Re: mm snapshot broken-out-2007-11-06-02-32.tar.gz uploaded - Build Failure at fsldma.c

Hi Andrew,

The build fails with error

  CC      net/9p/error.o
drivers/dma/fsldma.h:152: error: conflicting types for ‘in_be64’
include/asm/io.h:136: error: previous definition of ‘in_be64’ was here
drivers/dma/fsldma.h:157: error: conflicting types for ‘out_be64’
include/asm/io.h:135: error: previous definition of ‘out_be64’ was here
drivers/dma/fsldma.h:164: error: conflicting types for ‘in_le64’
include/asm/io.h:140: error: previous definition of ‘in_le64’ was here
drivers/dma/fsldma.h:169: error: conflicting types for ‘out_le64’
include/asm/io.h:145: error: previous definition of ‘out_le64’ was here
drivers/dma/fsldma.c:504: error: implicit declaration of function ‘bus_to_virt’
make[2]: *** [drivers/dma/fsldma.o] Error 1
make[1]: *** [drivers/dma] Error 2
make: *** [drivers] Error 2

This error is caused by the patch add-dma-engine-driver-for-freescale-mpc85xx-processors.patch

The following patch solves the conflict types error, but the bus_to_virt
is under the CONFIG_PPC32 ifdef and we had a discuss on the same for the
availability of the function for ppc64 at http://lkml.org/lkml/2007/10/17/524
