commit dc7019b7d0e188d4093b34bd0747ed0d668c63bf upstream.

Adds a new function tee_shm_alloc_kernel_buf() to allocate shared memory from a kernel driver. This function can later be made more lightweight by unnecessary dma-buf export.

5.10 contains follow-up patches actually using the export, but 4.19 does not. I believe it should be dropped from 4.19.

That's correct. Those follow-up patches that made use of this function were only needed back to 5.4.
