Bug description:
SRU Justification
[Impact]
The Google Kubernetes Engine team requested a GKE image with 64K pages and
GB300 support. This patchset targets noble:linux-gcp, noble:linux-gke, and
plucky:linux-gcp to keep all three kernels in sync with respect to NVIDIA
Grace.
[Fix]
The work for adding the 64K page size support to noble:linux-gke was completed
by [1].
Add the GB300 support by applying the latest upstream patches cataloged
here [2] on September 25, 2025.

[Test Plan]
Basic Grace checkout will be performed in house. Further testing
will be done by Google in their Grace-enabled environment once available.
[Regression potential]
The regression potential is considered low as the update consists
of only the patches added to [2] since April 25, 2025.
