Plus the following configuration changes:
+CONFIG_
+CONFIG_
+CONFIG_
+CONFIG_
+CONFIG_
In addition some modules need to be loaded by initramfs which requires changes to the initramfs-tools package.
The modules are:
nx-compress
nx-compress-crypto
nx-compress-
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.
You can find the commits at
git://git.
