Much better, but s390 images still fail to build:

arch/s390/kernel/suspend.c: In function 'pfn_is_nosave':
arch/s390/kernel/suspend.c:147:10: error: 'ipl_info' undeclared (first use in this function)
arch/s390/kernel/suspend.c:147:10: note: each undeclared identifier is reported only once for each function it appears in
arch/s390/kernel/suspend.c:147:27: error: 'IPL_TYPE_NSS' undeclared (first use in this function)
make[2]: *** [arch/s390/kernel/suspend.o] Error 1

The problem can be fixed by adding "#include <asm/ipl.h>" to
arch/s390/kernel/suspend.c in "s390/hibernate: fix save and restore
of kernel text section" or possibly in "nosave: consolidate
__nosave_{begin,end} in <asm/sections.h>". Or, of course,
in a separate patch, such as the one attached.
