From 4f47b4c9f0b711bf84adb8c27774ae80d346b628 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 5 May 2010 13:22:25 -0700 Subject: [PATCH] x86, acpi/irq: Define gsi_end when X86_IO_APIC is undefined My recent changes introducing a global gsi_end variable failed to take into account the case of using acpi on a system not built to support IO_APICs, causing the build to fail. Define gsi_end to 15 when CONFIG_X86_IO_APIC is not set to avoid compile errors. Signed-off-by: Eric W.
