From b683de2b3cb17bb10fa6fd4af614dc75b5749fe0 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 27 Sep 2010 20:55:03 +0200 Subject: genirq: Query arch for number of early descriptors sparse irq sets up NR_IRQS_LEGACY irq descriptors and archs then go ahead and allocate more. Use the unused return value of arch_probe_nr_irqs() to let the architecture return the number of early allocations. Fix up all users.
