SubjectRe: iso9660 endianness cleanup patch

Are you sure that the arguments of the following casting

> + return le16_to_cpu(*(u16 *)p);

> + return be16_to_cpu(*(u16 *)p);

> + return le32_to_cpu(*(u32 *)p);

> + return be32_to_cpu(*(u32 *)p);

are properly aligned ?
I did not revise the code to check it, but AFAIK improperly aligned
char* pointers cause problem with casting to pointers to 16/32-bit data
on some architectures (I heard of sucj a problem with alpha).

Maybe there was a reason that the original code did operate on bytes here...
