While I have been calling this a kernel regression, it might be that a great number of apparmor profiles need to be updated to accommodate the new security stuff that was introduced in kernel 4.14-rc2 (it missed -rc1 due to some issues, and it is not normal to include such major changes in anything other than -rc1). i.e. It might be that this is a non-backwards compatible kernel change.
Anyway, I know nothing about this area of the kernel, and will step back now.
To be able to proceed with my own work, I have compiled kernel 4.14-rc3 (and now 4.14-rc4) with apparmor disabled.

O.K. that is/was really important information.
