    When allocating pages for share memory with OP-TEE,
    the driver checks the page attribute (pte).
    The current checks only allow writealloc pages.
    i.MX 6SLL sets the page attribute to writeback.
    Relax this check to allow writealloc, writeback and writethrough.

    The driver maintains a list of shared memory buffers along with their
    mapped buffer id's in a global linked list. These buffers need to be
    unmapped after use by the user-space client.

    The global shared memory list is initialized to zero entries in the
    function amdtee_open(). This clearing of list entries can be a source
    for memory leak on secure side if the global linked list previously
    held some mapped buffer entries allocated from another TEE context.

    Fix potential memory leak issue by moving global shared memory list
    to AMD-TEE driver context data structure.

    This code was using get_user_pages*(), in a "Case 2" scenario
    (DMA/RDMA), using the categorization from [1]. That means that it's
    time to convert the get_user_pages*() + put_page() calls to
    pin_user_pages*() + unpin_user_pages() calls.

    Factor out a new, small release_registered_pages() function, in
    order to consolidate the logic for discerning between
    TEE_SHM_USER_MAPPED and TEE_SHM_KERNEL_MAPPED pages. This also
    absorbs the kfree() call that is also required there.

    There is some helpful background in [2]: basically, this is a small
    part of fixing a long-standing disconnect between pinning pages, and
    file systems' use of those pages.

    to TEE environment. REE kernel is required to verify that provided group
    identifier for group based logins matches calling processes group
    memberships.

    TEE specification only defines that the information passed from REE
    environment to TEE environment is encoded into on UUID.

    In order to guarantee trustworthiness of client UUID user space is not
    allowed to freely pass client UUID.

    Cleanup shared memory handing in TEE subsystem
    The highlights are:
    - Removing redundant or unused fields in struct tee_shm
    - Only assign userspace shm IDs for shared memory objects originating from
    user space

    * tag 'tee-cleanup-for-5.7' of https://git.linaro.org/people/jens.wiklander/linux-tee:
    tee: tee_shm_op_mmap(): use TEE_SHM_USER_MAPPED
    tee: remove redundant teedev in struct tee_shm
    tee: don't assign shm id for private shms
    tee: remove unused tee_shm_priv_alloc()
    tee: remove linked list of struct tee_shm

    The "index" is a user provided value from 0-USHRT_MAX. If it's over
    TEE_NUM_SESSIONS (31) then it results in an out of bounds read when we
    call test_bit(index, sess->sess_mask).
