From 63dc02bde6af1e41d28ebc3774c5f094f362e8c3 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 21 May 2012 17:54:01 +0900 Subject: sh: Kill off machvec IRQ hinting. Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead. It's also worth noting that the majority of boards had completely bogus values for their nr_irqs relative to their CPU and configurations, so this ends up correcting behaviour for quite a few platforms.
