# HG changeset patch
# User Jan Beulich <jbeulich@xxxxxxxxxx>
# Date 1301756302 -3600
# Node ID f9c85ce4795593b4f4599325181da78fa11ec5d3
# Parent 5f3b7050a203acc861c90efefb76adbb6c0b4058
x86/ACPI: __init-annotate
xen/arch/x86/acpi/boot.c consists of almost only code/data in .init.*,
so move the few bits that aren't into a new file and then use the
recently introduced .init.o mechanism to move all the literal strings
into .init.rodata.
