Subject: [PATCH 0/5] tee: shared memory cleanup
Date: Thu,  9 Jan 2020 13:36:46 +0100	[thread overview]
Message-ID: <20200109123651.18520-1-jens.wiklander@linaro.org> (raw)

Hi,

Here's a group of patches to the tee subsystem with cleanups and not so
urgent fixes related to tee shared memory.

- Unused parts of the shared memory object (struct tee_shm) are removed.
- Shared memory ids usable from user space are not assigned to driver
  private shared memory objects
- The TEE_SHM_USER_MAPPED is used instead of TEE_SHM_REGISTER to accurately
  tell if a shared memory object originates from another user space mapping.

Only unused "features" should be removed with this patch set, there should
be no change in behaviour or breakage with other code.

Thanks,
Jens
