[PATCH v3 1/9] context_tracking: Move guest exit context tracking to separate helpers

[Sean Christopherson]

From: Wanpeng Li <wanpen...@tencent.com>

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.
