William,
We were caught by the new centos kernel. 7.1.1 fixes a bug where the yum excludes for kernels was missing. If you get 7.1.1 installed, then you should not be prompted to install any newer kernels until they are released via smeupdates. In the meantime the -10 kernel and kmods are in smetest if you want to test them out. We are working hard to try to get 7.1.2 out the door as anyone that has updated to the -10 kernel will soon notice that pptp is broke.
