From 8843419048e500f8f38df555bca1bf7948804b7f Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Mon, 30 Mar 2009 16:03:18 +0300 Subject: [PATCH] KVM: VMX: Do not zero idt_vectoring_info in vmx_complete_interrupts(). We will need it later in task_switch(). Code in handle_exception() is dead. is_external_interrupt(vect_info) will always be false since idt_vectoring_info is zeroed in vmx_complete_interrupts().
