2f9b4c7 (bes2600: bounce SDIO TX buffers to avoid DMA OOB read) was
present in the cumulative single-patch but omitted from the per-series
reconstruction. Its absence caused KFENCE OOB hits in sdio_tx_work
(bes_sdio_memcpy_to_io_helper reads past tx_buffer->buf when align >
tx_buffer->len) leading to periodic TX workqueue stalls and latency
scatter under KFENCE_SAMPLE_INTERVAL=100ms.
Diagnosed during pkgrel=4 soak: 0 KFENCE hits in 6h on cumulative,
5-7/h on pkgrel=4 per-series. Root cause confirmed by diffing the
sdio_tx_work sg_set_buf call site in both patch sets.
