From: Michael Holzheu <[email protected]> On s390 there is a different KEXEC_CONTROL_MEMORY_LIMIT for the normal and the kdump kexec case. Therefore this patch introduces a new macro KEXEC_CRASH_CONTROL_MEMORY_LIMIT. This is set to KEXEC_CONTROL_MEMORY_LIMIT for all architectures that do not define KEXEC_CRASH_CONTROL_MEMORY_LIMIT.
