Just pushed a build with these changes 
https://git.stg.centos.org/rpms/raspberrypi2/c/94eb3c3ad1e3828a885cf5e5178fc78e21cca990?branch=c7-sig-altarch-kernel 

When it finishes, it should appear here 
https://buildlogs.centos.org/c7-kernels.armhfp/raspberrypi2/ (it should 
be in a few hours)

Let me know if you can test and how it went.

Thanks.

Pablo.
