From bf9d3cf73e8caf0b3ae0b7f508a9f251536f5ff4 Mon Sep 17 00:00:00 2001 From: Alex Nixon Date: Mon, 18 Aug 2008 22:17:08 -0700 Subject: [PATCH] xen: Fix bug `do_IRQ: cannot handle IRQ -1 vector 0x6 cpu 1' Following commit 9c3f2468d8339866d9ef6a25aae31a8909c6be0d, do_IRQ() looks up the IRQ number in the per-cpu variable vector_irq. This commit makes Xen initialise an identity vector_irq map for both X86_32 and X86_64.
