[Xen-devel] [PATCH 0/3] SSBD AMD via LS CFG Enablement

[Brian Woods <brian.woods@xxxxxxx>]

This series of patches is for enabling SSBD via the LS_CFG MSR for
family 15h-17h.  The first patch make it so that the information is
correctly displayed on boot.  The last two patches are for further
enablement for Xen switching SSBD on or off internally, or for further
control of SSBD for guests via the VIRT_SPEC_CTRL.

Note: these should be applied after Jan's patch:
x86/AMD: distinguish compute units from hyper-threads

Brian Woods (3):
  x86/spec-ctrl: add AMD SSBD LS_CFG in init print
  x86/spec-ctrl: Add defines and variables for AMD SSBD support
  x86/spec-ctrl: Add support for modifying SSBD AMD VIA LS_CFG MSR
