Hi,
This series is a follow-up to a prior patch to remove ACPI CPU hotplug AML from
PVH guests. Between now and then the working assumption for the corruption has
been identified to be more general than PVH. This series rewords the commit
message for that patch (which became patch 2 in this series), and includes a
patch 1 that prevents AML overflowing the MADT during execution of _GPE.
More details of the bug in patch1's commit message.
