I've tested it against a 32-bit host in a virtual machine and I
think it is enough to pass the build and the validation phase since
the `make check' does not seem to actually validate all targets but the
host so it should be fine.  I still need to improve the validation
when the kvx targets are validated on 32 bits hosts but I can do that
in a second time.

What is the process to get the changes merged?

I'll try that thanks, it will be faster than using a virtual machine.

This is a generated file, that is why the casts are everywhere. I'll
get rid of them when unnecessary.

Thanks
