Subject: KVM: x86: Simplify kvm_x86_ops->queue_exception parameter list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Patch-mainline: v4.13-rc1
Git-commit: cfcd20e5caad6ba552978c16ed8bed7edb0143cf
References: bsc#1077761
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.
