Why? This is clearly part of a larger series, but you've given those of
us who are subscribed to linux-mm absolutely no information about why
you want to do this.

I'm sorry, it's part of this patch: set
https://lore.kernel.org/lkml/20250502100049.1746335-1-jens.wiklander@linaro.org/
I'll CC a bit more in the next version of the patch set.
It's needed if the TEE subsystem is built as a load module.
Thanks,
Jens
