From: Zhang Yanfei <zhangyanfei@xxxxxxxxxxxxxx>
saved_max_pfn is used to know the amount of memory that the previous
kernel used. And for powerpc, we set saved_max_pfn by passing the
kernel commandline parameter "savemaxmem=".
The only user of saved_max_pfn in powerpc is read_oldmem interface.
Since we have removed read_oldmem, we don't need this parameter anymore.
