[Xen-devel] [PATCH 5/7] amd-iommu: __init-annotate

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

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.*.
