Public bug reported: SRU Justification
[Impact] Google has requested a backport of the following patchset: https://lore.kernel.org/all/20250228014416.3925664-1-vannapu...@google.com/ Targets include 6.8 onwards. [Fix] Backport the three patches in that patchset, as needed, to noble:linux-gcp, oracular:linux-gcp, and plucky:linux-gcp. [Test plan] Compile and boot test. Verification on Google's side is optional as this is a fairly isolated backport. [Where problems could occur] This fix affects TDX guest VMs which call the HLT instruction. An issue with this fix would be visible to the user as unexpected #VEs (virtualization exceptions) or unexpected interrupt behavior in their TDX guest VM.
