Subject: [PATCH v6 0/2] Enhance TEE kernel client interface

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.

Changes in v6:
- Reserve only half of GP implementation defined range for kernel space.

Changes in v5:
- Misc. renaming of variables.

Sumit Garg (2):
  tee: enable support to register kernel memory
  tee: add private login method for kernel clients
