This patch-set improve the Service-Call Logical Processor support for s390.
We tried to implement most of the comments that we got from the first patch

We still have code in hw/ since sclp supports features like console etc.
target-s390/op_helper.c now handles the basic checks for the instruction
itself and then passes control to the sclp code, which then parses the

Patch 1 is a bugfix for the current code, dealing with error and condition
code handling. Patch 2 adds/changes some base SCLP support. Patch 3 adds code
to support the SCLP commands Write Event Mask, Write Event Data, and
Read Event Data. Patch 4 and 5 add code to implement the commands for the
particular SCLP events Signal Quiesce (system_powerdown), and ASCII Console
Patch 6 (s390: make sclp ascii console the default) is currently optional
as it requires a kernel fix in the guest
KVM: s390: Perform early event mask processing during boot)

Heinz Graalfs (4):
