Date: Thu, 30 Apr 2009 20:01:29 -0400 From: Tim Abbott <tabbott@....EDU> To: Sam Ravnborg <sam@...nborg.org> Cc: Linux kernel mailing list <linux-kernel@...r.kernel.org>, Anders Kaseorg <andersk@....edu>, Waseem Daher <wdaher@....edu>, Denys Vlasenko <vda.linux@...glemail.com>, Jeff Arnold <jbarnold@....edu>, Ingo Molnar <mingo@...hat.com>, Thomas Gleixner <tglx@...utronix.de>, "H. Peter Anvin" <hpa@...or.com>, Tim Abbott <tabbott@....edu> Subject: [PATCH 02/11] x86: Use section .data.page_aligned for the idt_table. The .data.idt section is just squashed into the .data.page_aligned output section by the linker script anyway, so it might as well be in the .data.page_aligned section. This eliminates all references to .data.idt on x86.
