[S390] nss: Free unused memory in kernel image.
With CONFIG_SHARED_KERNEL the kernel text segment that might be in a read only memory sections starts at 1MB. Memory between 0x12000 and 0x100000 is unused then. Free this, so we have appr. an extra MB of memory available. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
