Well, that's the rub - RHEL7 have never had that upstream fix - i.e. the 
el7.4 kernel (3.10.0-693.el7) has 
'EXPORT_SYMBOL_GPL(__cachemode2pte_tbl)' as does the el7.5b kernel 
(3.10.0-830.el7) ...

The Nvidia driver builds/installs OK on el7.4 - but not on el7.5b

I'll report this to Red Hat anyway ...
