Bug Description

[Impact]

* Kernel OOPS encountered on 32-bit kernels due to commit cd0e9ab from
  git://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-gcp/+git/lunar

[Fix]

* Clean cherry pick from linux-next, commit 3e3255265291

[Test Case]

* Compile tested
* Boot tested
* To be tested by Google

[Where things could go wrong]

* Low chance of regression, isolated fix slightly modifying when value becomes
  available.

Removing Jammy from nominations as jammy:linux-gcp-6.2 and jammy:linux-aws-6.2 will be getting the patch via lunar:linux-gcp and lunar:linux-aws respectively.

This bug is awaiting verification that the linux-gcp/6.5.0-1008.8 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-mantic-linux-gcp' to 'verification-done-mantic-linux-gcp'. If the problem still exists, change the tag 'verification-needed-mantic-linux-gcp' to 'verification-failed-mantic-linux-gcp'.

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!

Verified to boot successfully. 32-bit machines otherwise not used on GCP, anyway.
