From a50abc3b2b469ee80bc0f9ef5b6d457ef72659a9 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 5 Sep 2012 20:00:52 +0300 Subject: [PATCH] KVM: use symbolic constant for nr interrupts interrupt_bitmap is KVM_NR_INTERRUPTS bits in size, so just use that instead of hard-coded constants and math.
