Bruce Rogers df8a80613e Accepting request 520017 from home:bfrogers:branches:Virtualization
A few post v2.10 patches needed to fix issues identified too late to get in. Also enable seccomp for all arch's we build for, and use better package references for rdma support

Subject: [PATCH] s390-ccw: Fix alignment for CCW1
The commit 198c0d1f9df8c4 s390x/css: check ccw address validity
exposes an alignment issue in ccw bios.
According to PoP the CCW must be doubleword aligned. Let's fix
this in the bios.
