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 <tabbott@ksplice.com> Cc: Ingo Molnar <mingo@redhat.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
