From 84b4be57ae17f8c0b3c1d8629e10f23910838fd7 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Tue, 12 Dec 2017 16:56:06 +0000 Subject: arm_pmu: note IRQs and PMUs per-cpu To support ACPI systems, we need to request IRQs before we know the associated PMU, and thus we need some percpu variable that the IRQ handler can find the PMU from. As we're going to request IRQs without the PMU, we can't rely on the arm_pmu::active_irqs mask, and similarly need to track requested IRQs with a percpu variable.
