It's actually coming from the default dist tag (in the
/etc/rpm/macros.dist) :
%dist .el7.centos

So when you build with mock , you can define yourself a specific dist
tag with "--define 'dist .el7' "

Well, still something we need to find a workaround for , and I wrote
initially a mail for the newer kernels to be tested :
https://lists.centos.org/pipermail/arm-dev/2016-January/001597.html
(see the part about generating initramfs with dracut and then editing
/boot/extlinux.conf)

Cool. I have also already rebuilt it (kernel-4.4.2-300.el7.armv7hl.rpm)
Are the patches under GPL licenses and somewhere to be seen ? If you
have to patch the Fedora kernel, that means that even Fedora doesn't
have it at the moment, so wondering why.

Thanks a lot for having a look at this ! I'm pretty sure that a lot of
people will find that useful
