Hi all,
This long patch series was motivated by backporting Jaedon's changes which add a proper ioctl compatibility layer for 32-bit applications running on 64-bit kernels. We have a number of Android TV-based products currently running on the 4.9 kernel and this was broken for them.
Thanks to Robert McConnell for identifying and providing the patches in their initial format.
In order for Jaedon's patches to apply cleanly a number of changes were applied to support those changes. If you deem the patch series too big please let me know.
Thanks
