> This function is used by sparc, powerpc tile and arm64 for compat
> support. The patch adds a generic implementation with a wrapper for
> PowerPC to do the u32->int sign extension.
> 
> The reason for a single patch covering powerpc, tile and sparc is to
> keep it bisectable, otherwise kernel building may fail with mismatched
> function declarations.
