[GIT PULL] updated exynos-drm-fixes

[Dave Airlie]

Hi Inki,

how urgent is this? Linus isn't really up for something this large
post -rc7, major regressions or oops fixes only at this point.

If its not urgent can we just stick it in -next and if needs be you
can get stable on required patches.

Dave.

> this patch set includes the following:
> - change exynos gem allocation interface.
>   . this patch makes non-contiguous memory allocation request allocate pages
>     from highmem through alloc_page() with GFP_HIGHUSER_MOVABLE because
>     cpu may read garbage data from cache once gpu operation is completed with
>     allocated pages.
>     shmem_read_mapping_page_gfp() first tries to allocate pages from page
>     cache so if pages are alloated from page cache then these pages could
>     have valid line and we had faced with this issue.
> - check if framebuffer and gem size are valid or not.
>   . with addfb or addfb2 request by user, invalid framebuffer or gem size
>     could be sent into kernel side so this could induce invalid memory
>     access by dma of a device. so this patch checks if framebuffer and
>     gem size are valid or not.
> - add exception codes to vidi module.
>   . edid data from user should be allocatd and copied into vidi context and
>     also freed with disconnection.
> - and code clean.
>
> please let me know it there is any problem.
> Thanks.
