Hi,                                                                                 

The helper functions bio_add_XXX_page() returns the length which is
unsigned int but the return type of those functions is defined
as int instead of unsigned int.

This is an attempt to fix the return type of those functions
and few callers. There are many places where this fix is needed
in the callers, if this series makes it to the upstream I'll convert
those callers gradually.

Any feedback is welcome.
