# User Jan Beulich <jbeulich@xxxxxxxxxx>
# Date 1301756255 -3600
# Node ID 5f3b7050a203acc861c90efefb76adbb6c0b4058

amd-iommu: __init-annotate

Besides marking a few more items __init/__initdata, use the recently
introduced .init.o mechanism to move all the literal strings into
.init.rodata in those files that consist of only contributions to
.init.*.
