Al asked: BTW, why does sparc64 export put_fs_struct?  Grepping the
kernel tree did not show any users of an exported put_fs_struct - so
drop the export.

Use sparc64 version of scatterlist.h.

There are three main differences:
    dma_addr_t replaces __u32
    dma_address replaces dvma_address
    dma_length replaces dvma_length

dma_addr_t is a u32 on sparc32.

Boot tested on sparc32.

This broke sparc64 in various ways.

Add an empty dummy hook in sparc32's prom_32.c so that we
can potentially handle things on that side similarly, and
in particular avoid a prom_common.c ifdef :-)

Without fancy makefile rules it's not straightforward
to prevent both arch/sparc/kernel/audit.o and lib/audit.o
from both being used on sparc32.

Since arch/sparc/kernel/audit.c is identical to lib/audit.c
except some CONFIG_COMPAT protected sections of code, just
use it on sparc32 too as that's the simplest way to fix
this.
