From 9d25d4db81833029d30b7b03cc1000cbbe09e192 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Mon, 21 Jul 2008 18:41:26 +0100 Subject: [PATCH] x86: BUILD_IRQ say .text to avoid .data.percpu When I edit the x86_64 Makefile to -fno-unit-at-a-time, bootup panics on 0xCCs in IRQ0x3e_interrupt(): IRQ0x20_interrupt etc. have got linked into .data.percpu. Perhaps there are other ways of triggering that: specify ".text" in the BUILD_IRQ() macro for safety. I've been using -fno-unit-at-a-time (to lessen inlining, for easier debugging) for a long time.
