[PATCH v7 0/4] ARM SMC Calling Convention interface

Jens Wiklander [off-list ref] writes:

This patch set is based on the Generic TEE subsystem v6 patchset
(https://lwn.net/Articles/662495/) sent out a some time ago. By isolating
the ARM SMC Calling Convention patches that are useful for other purposes
than to support the Generic TEE subsystem some complexity is removed from
that patch set.

This patch set adds a common interface to do an SMC or HVC following ARM
SMC Calling Convention. The interface is implemented for both the arm and
arm64 architectures and updates the PSCI driver to use this interface
instead for firmware communication.

Kevins previous Tested-by tag isn't included as the changes in the config
variables may affect some of the builds.

OK, I applied this on top of v4.4-rc6 and pushed it through another
round of build[1] and boot[2] testing and things look fine.
