More and more functionality from the early boot phase gets carried over to the decompressor. With this the complexity of the code and thus the chance to introduce bugs increases. In order to be able to debug these early boot bugs the distributions have to package the decompressors vmlinux together with the other debuginfos. However for that the distributions require the vmlinux to contain a build-id. Per default the section containing the build-id is placed first in the section table. So make sure to move it behind the .text section otherwise the image would be unbootable. Signed-off-by: Philipp Rudo <prudo@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
