When loading the dump-capture kernel, in some architectures(mips/ppc/ppc64), we should add the parameter "savemaxmem=" in the dump-capture kernel commandline to tell the new kernel the amount of memory that the previous kernel used. Then in the dump-capture kernel, we parse this parameter and assign the value to saved_max_pfn. In these architectures, the only user of saved_max_pfn is the read interface read_oldmem for /dev/oldmem. But, no one actually uses the /dev/oldmem interface. And we have decided to remove the /dev/oldmem interface. A kernel side patch to remove this interface have been sent. See https://lkml.org/lkml/2013/5/24/451. So in kexec-tools, we don't need to pass this parameter anymore. This patchset aims to remove the related variables and funtions in kexec-tools.
