Subject: [PATCH v2 14/15] x86: Use section .data.page_aligned for the idt_table.
Date: Tue, 28 Apr 2009 13:01:01 -0400 [thread overview]
Message-ID: <1240938062-3264-15-git-send-email-tabbott@mit.edu> (raw)
In-Reply-To: <1240938062-3264-14-git-send-email-tabbott@mit.edu>
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.
