Public bug reported:
This PR adds nine commits covering content merged into linux-nvidia-bos
after the snapshot used to create the original 7.3 branch.
The comparison covers 7.0-bos through 462a1f4 (October 28), against the
original migration ledger ending at a7fce78. Because BOS history was
rewritten, the comparison identified 20 candidate commits: 15 new items
and five previously reviewed patches appearing under different SHAs.
All 20 are accounted for below: nine picks, seven already covered by
upstream code in 7.3, three BOS release-metadata commits, and one patch
for the intentionally removed CXL reset series.
• Target base: 9f23faf
• Tested PR head: d28bba1
• Branch: 73_post_creation_pr_sync_70bos
Content included in this PR
Six commits are forward-ported from BOS, and three QSPI commits are
picked directly from upstream. The table follows git-log order, newest
first.

Same patch as previously reviewed a7fce781b943. It fixes the old downstream CXL

Build and package verification
Full Ubuntu 26.04 package builds passed at PR head d28bba1:
Configuration Build method Result
━━━━━━━━━━━━━━━━━━ ━━━━━━━━━━━━━━━━━━━━━━━ ━━━━━━━━
arm64, 4K pages Native build on arm64 Passed
────────────────── ─────────────────────── ────────
arm64, 64K pages Native build on arm64 Passed
────────────────── ─────────────────────── ────────
amd64 Cross-build on arm64 Passed
Verification included compilation of all enabled modified objects,
kernel/module linking and modpost, package architectures and dependencies,
payload ownership, and matching packaged configs and Module.symvers.
Builds used do_zfs=false, do_mstflint_access=false, and do_nvidia-
fs=false, with packaging dependencies adjusted for the omitted companion
packages. The amd64 cross-build used the existing build-only annotation-
checker allowance for known cross-compiler/native-CPU probe differences.
Delivery source was unchanged by these build accommodations.
The arm64 64K packages and matching headers were preserved for hardware
testing.
Strata runtime testing
The arm64 64K packages from this exact PR head were installed and tested
on a Strata system running Ubuntu 26.04.
• Booted 7.3.0-1001-nvidia-64k and verified the 65,536-byte page size and
matching build artifacts.
• Built NVIDIA driver 620.70.01; it loaded automatically and bound all four
GPUs.
• Ran CUDA vector-add workloads on all four GPUs: 32 launches per GPU, each
processing 1,048,576 floats, with results verified.
• Exercised CPU-affinity execution on CPUs 0–3 and 348–351, 256 MiB of memory
at 64K-page boundaries, and a verified 128 MiB disk write/fsync/read cycle.
• Booted a real KVM guest using UEFI, four vCPUs, 2 GiB RAM, the 7.3 64K
kernel, and a minimal BusyBox initramfs. Guest CPU/kernel checks and clean
shutdown passed.
• Confirmed all 352 CPU governors were performance. Available RAM differed from
the 7.0 baseline by only 2 MiB.
• Found no host oops, panic, lockup, RCU stall, GPU Xid, or I/O error in the
captured boot/workload logs.
