From 866a6dadbb027b2955a7ae00bab9705d382def12 Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Tue, 4 May 2021 17:27:28 -0700 Subject: [PATCH] context_tracking: Move guest exit context tracking to separate helpers Provide separate context tracking helpers for guest exit, the standalone helpers will be called separately by KVM x86 in later patches to fix tick-based accounting.
