Kernel 4.15 is now in 18.04 daily builds. LP defects shows this as Fix Released. This should be closed.

We had an issue with paste instruction which is disabled in < DD 2.2. Now tested VAS/NX successfully with the upstream kernel on DD 2.2. All patches needed to enable NX842 are included in upstream 4.14 and 4.15.

NX842 functionality will work only on DD 2.2 and later. So skiboot 5.10 or later is needed to use NX842.

Verified NX842 compression/decompression with 18.04 kernel (4.15.7).
