From: Heiko Carstens <[EMAIL PROTECTED]> [S390] Bad kexec control page allocation.
KEXEC_CONTROL_MEMORY_LIMIT is an unsigned long value and therefore should be defined as one. Otherwise the kexec control page can be allocated above 2GB which will cause a specification exception on the sam31 instruction in the s390 kexec relocation code.
