Earlier this patch-set was part of TEE Trusted keys patch-set [1]. But since these are completely independent enhancements for TEE kernel client interface which can be merged separately while TEE Trusted keys discussions are ongoing.
Patch #1 enables support for registered kernel shared memory with TEE.
Patch #2 enables support for private kernel login method required for cases like trusted keys where we don't wan't user-space to directly access TEE service.
