DLPX-98112 linux-kernel-generic: rebase Delphix patchset onto Ubuntu-hwe-7.0-7.0.0-28.28_24.04.1

[lyriclake]

Rebases the Delphix patchset onto Ubuntu tag Ubuntu-hwe-7.0-7.0.0-28.28_24.04.1, replacing the previous base
Ubuntu-hwe-6.17-6.17.0-40.40_24.04.1. Recreates the rebase that linux-pkg/develop/update-package/linux-kernel-generic failed to complete.

Field	Value
Upstream tag	Ubuntu-hwe-7.0-7.0.0-28.28_24.04.1 (917185778ef2b3cb674c703dfd055eb0c4af67de)
Previous base	Ubuntu-hwe-6.17-6.17.0-40.40_24.04.1 (063d17a50448cbb5ef703221a62f6af6d1fb78d1)
Patchset	9 patches (0 dropped of 9)
Conflicts resolved	1
Jira	DLPX-98112

Note: GitHub will show "This branch has conflicts that must be resolved" and
a diff against the whole Ubuntu bump. Both are expected: this branch does not
descend from develop — the kernel forks are rebased onto each new
Ubuntu tag with git cherry-pick, not merged. Review the patchset commits, not
the aggregate diff. Landing is a force-push, not a GitHub merge.

8f4441107409 — Extract PKG_ABI from mutated string

Conflicting: include/asm-generic/mshyperv.h
Upstream cause: 56f727d2cc7a — UBUNTU: SAUCE: (no-up) hv: Supply vendor ID and package ABI
Verdict: RE_APPLY — Ubuntu SAUCE relocated the #ifndef PKG_ABI block from before hv_do_rep_hypercall() to after it while re-applying the SAUCE stack onto the 7.0 mainline; content unchanged. New upstream still defines PKG_ABI as a bare unquoted integer, so the Delphix ABI-string mutation handling is still needed. Ported the same string-mutation logic to the relocated position verbatim.

Testing Done

ab-pre-push build #14705: FAILURE

• Build: https://selfservice-jenkins.eng-tools-prd.aws.delphixcloud.com/job/appliance-build-orchestrator-pre-push/14705/
• Tested: linux-kernel-generic@e92af378a006 (against develop)
• Suites: build — FAILURE. ipu7-drivers DKMS module failed to compile against the new kernel's V4L2 subdev API (drivers/media/i2c/ov02c10.c: error: implicit declaration of function 'v4l2_subdev_state_get_format' / 'struct v4l2_subdev' has no member named 'entity') — a stale Ubuntu-side DKMS pin, unrelated to this patchset, that our build tooling doesn't exclude. Fix: DLPX-98296 linux-kernel-generic pre-push build fails: ipu7-drivers DKMS module missing do_ipu7=false disable flag linux-pkg#405 (DLPX-98296).

ab-pre-push build #14718: IN PROGRESS

• Build: https://selfservice-jenkins.eng-tools-prd.aws.delphixcloud.com/job/appliance-build-orchestrator-pre-push/14718/
• Tested: linux-kernel-generic@e92af378a006, linux-pkg@065c38acf7f7, zfs@e62b28d4bbc4 (against develop)
• Status: running — re-test with the linux-pkg do_ipu7=false fix (PR #405) and the zfs sockaddr_unsized fix (PR #2305, needed because this hwe-7.0 kernel's headers carry the same API change as aws's) both included as extra repos; re-run recording in completed mode once finished.
