Subject: [PATCH 07/19] KVM: s390: rename private structures
From: Christian Borntraeger <borntraeger@...ibm.com>
While doing some tests with our lcrash implementation I have seen a
naming conflict with prefix_info in kvm_host.h vs. addrconf.h
To avoid future conflicts lets rename private definitions in
asm/kvm_host.h by adding the kvm_s390 prefix.
