SRU Justification
[Impact]
Google has requested a backport of the following commits:
22cc5ca5de52 ("x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT")
9f98a4f4e721 ("x86/tdx: Fix arch_safe_halt() execution for TDX VMs")
Targets include 6.8 onwards.
[Fix]
Backport the patches as needed to noble:linux-gcp and later kernels.
[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.

This bug is awaiting verification that the linux-gcp-
fips/6.8.0-1035.37+fips1 kernel in -proposed solves the problem. Please
test the kernel and update this bug with the results. If the problem is
solved, change the tag 'verification-needed-noble-linux-gcp-fips' to
'verification-done-noble-linux-gcp-fips'. If the problem still exists,
change the tag 'verification-needed-noble-linux-gcp-fips' to

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!
