Public bug reported:
SRU Justification
[ Impact ]
* 9f98a4f4e721: "x86/tdx: Fix arch_safe_halt() execution for TDX VMs"
pulled in this SRU cycle causes build issues without 22cc5ca5de52:
"x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT". Both
patches are required on the Azure kernel due to its kernel
configuration.
[ Fix ]
* Backport 22cc5ca5de52: "x86/paravirt: Move halt paravirt calls under
CONFIG_PARAVIRT" from upsteram
[ Test Plan ]
* Compile tested
[ Where problems could occur ]
* Regression risk is quite low, and worse if this patch isn't included
as the kernel won't actually build. Possibly regressions would be to
hypervisor support in circumstances where the code that was moved needs
to rely on CONFIG_PARAVIRT_XXL.
