Hi folks,
While hacking on the GIC flow handlers, I grew increasingly suspicious of handle_percpu_devid_fasteoi_ipi() and thus did a bit of digging. AFAICT it isn't actually needed and handle_percpu_devid_irq() would suffice. Argumentation is in patch 1.
Tested on my Juno (GICv2) and eMAG (GICv3).
Whichever way this goes I owe Marc some pastries, given I either - Missed something and created some noise - Turned my brain off back when reviewing this flow handler so maybe just start with pinging me what you want...
