Comment 4 for bug 1454687

All patches cleanly cherry-pick into 3.19.

The following config options are already set in Ubuntu:

CONFIG_ZSWAP=y
CONFIG_ZPOOL=y
CONFIG_ZBUD=y
CONFIG_ZSMALLOC=y
CONFIG_CRYPTO_ALGAPI=y
CONFIG_CRYPTO_DEV_NX=y
CONFIG_CRYPTO_DEV_NX_COMPRESS=m

I'll add the following:
+CONFIG_842_COMPRESS=m
+CONFIG_842_DECOMPRESS=m
+CONFIG_CRYPTO_DEV_NX_COMPRESS_CRYPTO=m
+CONFIG_CRYPTO_DEV_NX_COMPRESS_POWERNV=m
+CONFIG_CRYPTO_DEV_NX_COMPRESS_PSERIES=m

The only changes are build these as modules, and add 842_COMPRESS.

Does this work?

Thanks,
