[PATCH] powerpc: Fix mmap returning 64 bit addresses
The merge of syscalls.c & sys_ppc32.c (30286ef6e044bc3d9019c3d8b900572e3fa05e65)
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 ...
