From 98f65ad458441ea3a243395345811132ee850093 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Thu, 1 Mar 2018 15:15:13 +0100 Subject: x86/kvm/hyper-v: remove stale entries from vec_bitmap/auto_eoi_bitmap on vector change MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a new vector is written to SINx we update vec_bitmap/auto_eoi_bitmap but we forget to remove old vector from these masks (in case it is not present in some other SINTx).
