Title: add NX 842 hw compression patches Status in initramfs-tools package in Ubuntu: Fix Released Status in linux package in Ubuntu: In Progress Status in initramfs-tools source package in Vivid: In Progress Status in linux source package in Vivid: Fix Released Bug description: [Impact] Users of PowerPC processors with an NX coprocessor will not be able to use features like memory compression without this set of patches. [Test Case] Run kernel on a PowerPC processor with an NX coprocessor implementing 842 memory compression.

The modules are: nx-compress nx-compress-crypto nx-compress-platform nx-compress-pseries nx-compress-powernv 842-decompress -- Please add/include the patches for PowerPC NX coprocessor 842 memory compression. They're currently in Herbert Xu's upstream tree, and presumably he will send them up to Linus at the 4.2 merge window.
