I tested the new kernel on my Cubietruck and was able to boot after
manually generating the initramfs using the command

-----------------------------------------------------------------------------------------------------------------------------
dracut --verbose
/boot/initramfs-4.2.0-0.rc2.git0.1.centos.el7.armv7hl.img
4.2.0-0.rc2.git0.1.centos.el7.armv7hl
-----------------------------------------------------------------------------------------------------------------------------

I have the package dracut-config-generic-033-240.el7.armv7hl
installed. Make sure you have it too. I am not sure if that's the
source of the problem.

The entry in /boot/extlinux/extlinux.conf created by the rbfkernelup
yum plugin is
-----------------------------------------------------------------------------------------------------------------------------
label Derived from Red Hat Enterprise Linux 7.1 (Source)
4.2.0-0.rc2.git0.1.centos.el7.armv7hl
    kernel /vmlinuz-4.2.0-0.rc2.git0.1.centos.el7.armv7hl
    append enforcing=0 root=UUID=34fa4504-d4ae-4d17-9c07-4c56a5f8f614
    fdtdir /dtb-4.2.0-0.rc2.git0.1.centos.el7.armv7hl
    initrd /initramfs-4.2.0-0.rc2.git0.1.centos.el7.armv7hl.img
-----------------------------------------------------------------------------------------------------------------------------
You will have the change the UUID as per your board.

However, I am not able to use ethernet with the new kernel. I haven't
looked into it in detail but preliminary debugging shows the module
stmmac_platform.ko not loading. I get this error
-----------------------------------------------------------------------------------------------------------------------------
