From: Christian Borntraeger <[email protected]> KVM on s390 does not support the ESA/390 architecture. We refuse to change the architecture mode and print a warning. This patch removes the printk for several reasons:
o A malicious guest can flood host dmesg o The old message had no newline o there is no connection between the message and the failing guest This patch simply removes the printk. We already set the condition code to 3 - the guest knows that something went wrong.
