[CentOS] New C7 kernel ABI and kmods

All,

This is just a heads-up that the new C7 update kernel breaks ABI 
compatibility, at least as far as using the ELrepo nVidia drivers is 
concerned.  I have posted more details to the ELrepo list; but since 
many folks use the Elrepo kmods I thought a heads-up would be appropriate.

If you use the ELrepo nvidia kmod you will either need to hold off on 
the kernel update or uninstall the nvidia kmod.
