From 07e81d61605f885920f31634a65aace52beb97db Mon Sep 17 00:00:00 2001 From: Tim Abbott Date: Wed, 16 Sep 2009 16:44:29 -0400 Subject: [PATCH] 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. Signed-off-by: Tim Abbott Cc: Ingo Molnar Signed-off-by: H.
