[PATCH 0/2] Fix tee: optee: add dynamic shared memory support

[Jens Wiklander]

Hi,

These two patches complements the previously posted patchset
"tee: optee: add dynamic shared memory support"
https://lwn.net/Articles/740242/

Tests are added to see that the registered shared memory cache attributes
are compatible with OP-TEE in secure world. Under normal circumstances they
will be compatible, but if memory has been previously mapped from a device
with special page attributes it could lead to trouble.

Thanks,
Jens
