From 0aa67255f54df192d29aec7ac6abb1249d45bda7 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Mon, 26 Nov 2018 16:47:29 +0100 Subject: x86/hyper-v: move synic/stimer control structures definitions to hyperv-tlfs.h We implement Hyper-V SynIC and synthetic timers in KVM too so there's some room for code sharing.
