From 4e3f77d8419b6787f3eb4d4f5178f459d693f9bb Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 11 Nov 2019 15:46:26 +0100 Subject: xen/mcelog: add PPIN to record when available This is to augment commit 3f5a7896a5 ("x86/mce: Include the PPIN in MCE records when available"). I'm also adding "synd" and "ipid" fields to struct xen_mce, in an attempt to keep field offsets in sync with struct mce. These two fields won't get populated for now, though.
