This seems to fix the issue, the Teclast X89 boots again and I've
also tested this on 2 other devices (one mixed mode Bay Trail one 64 bit
Cherry Trail device).

If I want to also test them, how do the 2 new series you've just posted come
into the mix here? :

"[PATCH 0/3] efi/x86: clean up and simplify runtime call wrappers"
"[PATCH 0/3] efi/x86: righten memory protections at runtime"

Regards,

Hans
