The goal is to land every deprecation currently listed in the release notes by the 26.11 ABI bump. Working back from there: any function to be removed in 26.11 needs to be marked __rte_deprecated by 26.07, and all in-tree users converted off it before the marker patch goes in so CI stays clean.
This series is the preparatory work for the rte_atomicNN_*() family under that plan. It does not yet add the __rte_deprecated marker; that's a separate follow-up once the remaining in-tree users are converted. Other items on the deprecation list (VXLAN_GPE, pipeline/table/port legacy API, the MAX enum fix, regexdev, pdump, TM locks) will follow as their own series on the same timeline. Patch 3 is the load-bearing change: the last lib/ caller of rte_atomic32_cmpset() is converted, clearing the way. Patch 7 drops RTE_FORCE_INTRINSICS entirely. With the option always on, the asm implementations of atomics, spinlock and byteorder become dead code. ~900 lines deleted; the patch most worth review attention. This makes it easier to flag the rte_atomicNN as deprecated since they are all in one place. Patch 2 retires the rte_smp_*mb deprecation notice (open since 2021) by reimplementing those APIs as wrappers over rte_atomic_thread_fence, preserving the API for readability. Patches 5 and 6 convert and clean up two driver users (bonding, nbl). Patch 4 is a preparatory workaround for a pre-existing GCC bitfield -Wmaybe-uninitialized false positive in net/zxdh, surfaced by the improved compiler visibility after patch 7. Placed ahead of patch 7 to keep every commit bisectable. Follow on patches will mechanically convert drivers. If driver writer fixes it themselves; all the beter.
