🎀 NAME 🎀

tmigr_cpu_activate — set this CPU active in timer migration hierarchy

---

🦋 SYNOPSIS 🦋

void tmigr_cpu_activate (void );

---

🌸 ARGUMENTS 🌸

• void — no arguments. that's it. literally nothing to pass, bestie 🫶

---

💖 DESCRIPTION 💖

so the call site is timer_clear_idle, and it gets called with interrupts disabled. that's the whole vibe check, no cap 😭 that's the entire description. short and sweet, she ate 💀

ngl it's giving "one-line legend" — but it's real, and the interrupts-disabled part is not a suggestion, so don't come for me 🙈
