[ Upstream commit 8d18ef04f940a8d336fe7915b5ea419c3eb0c0a6 ]
In the upcoming changes, the ELF_DETAILS macro will be extended with the ".modinfo" section, which will cause an error:
s390x-linux-ld: .tmp_vmlinux1: warning: allocated section `.modinfo' not in segment s390x-linux-ld: .tmp_vmlinux2: warning: allocated section `.modinfo' not in segment s390x-linux-ld: vmlinux.unstripped: warning: allocated section `.modinfo' not in segment
This happens because the .vmlinux.info use :NONE to override the default segment and tell the linker to not put the section in any segment at all.
To avoid this, we need to change the sections order that will be placed in the default segment.
