+- update to criu 3.4:
+  New features:
+  * Support for s390x architecture
+  Improvements:
+  * Unexpected death of restored tasks is reported with more
+    details in logs
+  * Merged many images containing info about files into one big
+    files.img
+  * When helper utility fails (ip, iptables, tar) its name is
+    printed in logs
+  Bugfixes:
+  * Compilation failed on newer glibcs (ucontext_t)
+  * Dying helper task could deadlock the restore process
+  * Install-related makefile variables weren't configurable for
+    distro build
+  * SIT (ipv6-to-v4 tunnel) presence on host blocked dump of any
+    containers
+  * Potential NULL dereference when dumping net namespace
+  * Dump via page server might not work across different criu
+    versions
+  * Failure to restore a subtask could be ignored by the restore
+    command
+  * EOF on page-server socket wasn't handled
+- Dropped obsoleted patch:
+  criu-correct-ppc64-AT_VECTOR_SIZE_ARCH.patch
+- Add s390x to exclusivearch
