okay so this is poison_setup(9), straight out of the Kernel API Manual, and it's basically the little routine that keeps your poison registers updated ✨

poison_setup — update poison registers. that's the whole assignment, periodt 💅

---

🦋 DESCRIPTION 🦋

Update poison registers as per DDR mapping upon write of the address location the fault is injected.

translation for the group chat: when there's a write to the address location where the fault is injected, poison_setup() updates the poison registers according to the DDR mapping 🔥 no extra side quests, no invented lore, just that.
