[PATCH] kexec: s390 support
Add kexec support for s390 architecture. From: Milton Miller <miltonm@bga.com> - Fix passing of first argument to relocate_kernel assembly. - Fix Kconfig description. - Remove wrong comment and comments that describe obvious things. - Allow only KEXEC_TYPE_DEFAULT as image type -> dump not supported.
