The merge of syscalls.c & sys_ppc32.c (30286ef6e0)
broke mmap, if the mmap returned a 64 bit address.
do_mmap2 was taking the return value from do_mmap_pgoff (an unsigned long), and
storing it in an int, before returning it to sys_mmap as an unsigned long. So
we were losing the high bits of the address.
You would have thought the compiler could catch this for us ...

This makes ppc use the syscalls.c from arch/powerpc/kernel, exports
copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc),
and consolidates the sys_fadvise64_64 implementations for 32-bit.
