It will be enabled automatically on all archs that set
ARCH_HAS_DEBUG_VM_PGTABLE, which we do for s390 unconditionally.
Also, DEBUG_VM has to be set, which we have only in the debug config.
So only the s390 debug config will have it enabled, you can check
dmesg for "debug_vm_pgtable" to see when / where it was run, and if it
triggered any warnings.

I also checked with the v3 series, and it works fine for s390.
