Subject: kbuild: link vmlinux.o before kallsyms passes
X-Git-Url: http://git.maemo.org/git/?a=commitdiff_plain;h=310f8243a602e9ae950e81b17cbd18a4246674f9;p=h-e-n

kbuild: link vmlinux.o before kallsyms passes

link vmlinux.o so we may report section mismatch bugs before
we start with the real link - that may error out.
