Message-Id: <1226294895.5478.5.camel@brick> Date: Sun, 09 Nov 2008 21:28:15 -0800 From: Harvey Harrison <harvey.harrison@...il.com> To: Ingo Molnar <mingo@...e.hu> Cc: "H. Peter Anvin" <hpa@...or.com>, Thomas Gleixner <tglx@...utronix.de>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH] x86: x86_32 has its own irq_regs definition Impact: prevent second percpu define of unused irq_regs Arches that have their own irq_regs definition are expected to define ARCH_HAS_OWN_IRQ_REGS or else a generic (unused) set will also be defined in lib/irq_regs.c Sparse noticed the unused generic one had no prototype: lib/irq_regs.c:15:1: warning: symbol 'per_cpu____irq_regs' was not declared. Should it be static?
