[PATCH stable 4.9 00/21] Unbreak 32-bit DVB applications on 64-bit kernels

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
