The workaround has no Kconfig option: drivers/irqchip/irq-gic-v3.c passes the GICD_IIDR value to gic_enable_quirks(), which compares it against gic_quirks[]; the matching quirk, gic_enable_quirk_arm64_2941627(), enables a static branch. The table already records GIC-driver workarounds that have no Kconfig symbol as "N/A", for example the NVIDIA T241-FABRIC-4 row, whose workaround is likewise in the GIC driver. Set the Kconfig column to "N/A" for this row. Leave the row in place: it is the tree's only record of this erratum. No functional change. The change and this changelog were written with the help of an LLM assistant (Hermes Agent); I reviewed both and am responsible for them.
