This reverts commit55a5542a54
("s390/hibernate: fix error handling when suspend cpu != resume cpu"). It added sclp_early_printk_force() which is no longer used since commit394216275c
("s390: remove broken hibernate / power management support"). No hibernate - no problem. Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
