these patch sets fix some issues to gem and vidi driver and include the following: - fixes cache issue according to gpu operation . shmem_read_mapping_page_gfp function first tries to allocate pages from page cache and if the allocation is done from page cache the the pages could have valid cache line so cpu may read garbage data from cache after gpu operation is completed. - use edid data from user propely and add some exception codes - fixes releasing issue to exported gem buffer into dmabuf - and code clean
Thanks.
