From: Ekaterina Tumanova <tuman...@linux.vnet.ibm.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit b75f4c9afac2604feb971441116c07a24ecca1ec upstream.
s390 documentation requires words 0 and 10-15 to be reserved and stored as
zeros. As we fill out all other fields, we can memset the full structure.
