However afterwards common code functions are called which might access percpu data structures. Since the lowcore contains e.g. the percpu base pointer this isn't a good idea. So fix this by copying the hibernating cpu's lowcore to absolute address zero. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky --- Reading git-diff-tree failed
