[PATCH] uml: make 64-bit COW files compatible with 32-bit ones
This is the minimal fix to make 64-bit UML binaries create 32-bit compatible COW files and read them. I've indeed tested that current code doesn't do this - the code gets SIGFPE for a division by a value read at the wrong place, where 0 is found.
