let's update the pid only in the KVM_RUN ioctl.
In addition, don't do a synchronize_rcu on startup (pid == 0).
This speeds up guest boot time on s390 noticably for some configs, e.g.
HZ=100, no full state tracking, 64 guest cpus 32 host cpus.

injecting irqs manually to the list in sigp code.
SIGP stop is special because we have to check the

Paolo, Gleb,
the s390 queue has 3 fixes scheduled for 3.16.
The EFAULT fix fixes a bug that is only in kvm/next, and the
other fixes are long standing non-critical problems so no
cc stable.
Please apply.

Thanks.
David,
thanks for the review.
Are you ok with this change as well? The alternative is to shorten our
descriptions (in 1/11 s390: add sie exit reasons tables), which would make the
trace output less comprehensible, though.
