[PATCH v6 9/9] s390: vmlinux.lds.S: Reorder sections

[Alexey Gladkov]

Reorder the sections to be placed in the default segment. The
.vmlinux.info use :NONE to override the default segment and tell the
linker to not put the section in any segment at all.

Is there any reason why you didn't reorder the patches?

Oops! My bad. This patchset was added to linux-next and seems to be in
the correct order, but then it was removed and I seem to have lost this
change.
