This patch revert commit c83900393aa1 ("tee: Remove vmalloc page support")
As per the discussion back then: don't just blindly do the same dumb thing again and fix the interfae to actually pass in a page array, or iov_iter or an actually useful container that fits.
I suppose your are speaking about this discussion: https://lore.kernel.org/all/20221002002326.946620-3-ira.weiny@intel.com/
If I'm not mistaken, I should modify at tee_shm_register_kernel_buf API and register_shm_helper inernal function, right?
Seems that Jens has also pointed out the free part...
What about having equivalent of shm_get_kernel_pages in an external helper (to defined where to put it), could it be an alternative of the upadate of the tee_shm API?
Thanks, Arnaud
