s390: introduce .boot.preserved.data section compile time validation
Same as for .boot.data section make sure that .boot.preserved.data sections of vmlinux and arch/s390/compressed/vmlinux match before producing the compressed kernel image. Symbols presence, order and sizes are cross-checked. Signed-off-by: Vasily Gorbik <gor@linux.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
