Subject: vmlinux.lds.h: Replace RODATA with RO_DATA
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c82318254d15e5f83c75f60aedf2bb9eb408308f;p=linux.git

vmlinux.lds.h: Replace RODATA with RO_DATA

There's no reason to keep the RODATA macro: replace the callers with
the expected RO_DATA macro.
