Subject: [PATCH v6 1/4] KVM: x86: Simple kvm_x86_ops->queue_exception parameter
From: Wanpeng Li <wanpeng.li@...mail.com>
This patch removes all arguments except the first in kvm_x86_ops->queue_exception
since they can extract the arguments from vcpu->arch.exception themselves, do the
same in nested_{vmx,svm}_check_exception.
