DLPX-98112 linux-kernel-aws: rebase Delphix patchset onto Ubuntu-aws-7.0-7.0.0-1009.9_24.04.1

[lyriclake]

Rebases the Delphix patchset onto Ubuntu tag Ubuntu-aws-7.0-7.0.0-1009.9_24.04.1, replacing the previous base
Ubuntu-aws-6.17-6.17.0-1019.19_24.04.1. Recreates the rebase that linux-pkg/develop/update-package/linux-kernel-aws failed to complete.

Field	Value
Upstream tag	Ubuntu-aws-7.0-7.0.0-1009.9_24.04.1 (7fe9a458efaf211b5902f7f8e71d678a554334a6)
Previous base	Ubuntu-aws-6.17-6.17.0-1019.19_24.04.1 (6685d2a5d2a9b95b7ad26f4886a592f6f204da31)
Patchset	10 patches (0 dropped of 10)
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.

7104c91814c2 — 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 — Same resolution as generic (8f4441107409); see PR delphix/linux-kernel-generic#57. 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; conflict shape and diff were byte-identical to the generic fork's.

Testing Done

ab-pre-push build #14707: FAILURE

• Build: https://selfservice-jenkins.eng-tools-prd.aws.delphixcloud.com/job/appliance-build-orchestrator-pre-push/14707/
• Tested: linux-kernel-aws@69ffacf47d20 (against develop)
• Suites: build — FAILURE. zfs failed to compile against the new kernel (module/os/linux/zfs/sock.c:39:42: error: passing argument 2 of 'sock->ops->connect' from incompatible pointer type — expected struct sockaddr_unsized *, kernel API change from Linux 6.19 backported into this Ubuntu tag). Fix: https://github.com/delphix/zfs/pull/2305 (DLPX-98297).

ab-pre-push build #14717: IN PROGRESS

• Build: https://selfservice-jenkins.eng-tools-prd.aws.delphixcloud.com/job/appliance-build-orchestrator-pre-push/14717/
• Tested: linux-kernel-aws@69ffacf47d20, zfs@e62b28d4bbc4 (against develop)
• Status: running — re-test with the zfs sockaddr_unsized fix (PR #2305) included as an extra repo; re-run recording in completed mode once finished.
