[SRU][N:gcp/N:gke/P:gcp][PATCH 0/3] NVIDIA Grace update for Google (Sep 2025)

[Tim Whisonant]

BugLink: https://bugs.launchpad.net/bugs/2126453

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.
