gdb is hardly performance critical. Is that the only reason for the change?Right, gdb is not performance critical. gdb is the reason for moving it out of the union, performance is the reason for having it in kvm_run at all. There's only more reason to it: with a little tweaking in kuli, we'll be able to get rid of KVM_S390_SET_INITIAL_PSW ioctl with this change. That removes one oddity that makes us different from other platforms.
