From 6e99520bf47f9de2dc59b9fbbc5f932fca3a8086 Mon Sep 17 00:00:00 2001 From: Paul Durrant Date: Fri, 3 Jan 2020 17:06:03 +0100 Subject: [PATCH] x86/save: reserve HVM save record numbers that have been consumed... ...for patches not (yet) upstream. This patch is simply adding a comment to reserve save record number space to avoid the risk of clashes between existent downstream changes made by Amazon and future upstream changes which may be incompatible.
