The current logic for AMD SSBD context switches it on every

much as possible.

Hello,
The following series aims to remove running C code with GIF=0 on the AMD
vm{entry,exit} paths. As a result, the context switching of SSBD is
done when context switching vCPUs, and hence Xen code is run with the

First patch is the one strictly needed, but patches 2
Like on Intel AMD guests are now capable of setting SSBD on their own,
either from SPEC_CTRL or from VIRT_SPEC_CTRL. As a result the

Remove the Xen command line `spec-ctrl=ssbd` o
Since the VIRT_SPEC_CTRL.SSBD selection is no longer context switched
on vm{entry,exit} there's no need to use a synthetic feature bit for
it anymore.
Remove the bit and instead use a global variable.
No functional change intended.

support period has ended earlier this month, this is going to be the
final XenProject-coordinated release from this branch.

x86 has implemented a set of codes to process NUMA nodes. These
codes will parse NUMA memory and processor information from
ACPI SRAT table. But except some ACPI specific codes, most
of the process code like memory blocks validation, node memory
range updates and some sanity check can be reused by
Currently the maximum number of NUMA nodes is a hardcoded value.
This provides little flexibility unless changing the code.
Introduce a new Kconfig option to change the maximum number of
NUMA nodes conveniently. Also considering that not all
architectures support NUMA, this Kconfig option is only
There are some codes in x86/numa.c can be shared by common
architectures to implememnt NUMA support. Just like some
variables and functions to check and store NUMA memory map.
And some variables and functions to do NUMA initialization.
In this patch, we move them to common/numa.c and xen/numa.h

The sanity check of nodes_cover_memory is also a requirement of
