[S390] Bad kexec control page allocation.

Browse Source 
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.
