This patch tries to clarify the manpage in two aspects: It describes the meaning of kexec without an -e / -l / -f / -p option (i.e. only with kernel, initrd and command line). It also documents the difference between -f and normal kexec call better. I made the patch to clarify the manpage because there was some confusion in https://bugzilla.novell.com/show_bug.cgi?id=387601.
