powerpc: Fixes to get the merged kernel to boot on powermac.
This merges ppc_ksyms.c, puts back the actual do_execve call in sys_execve, makes init_MMU call find_end_of_memory rather than ppc_md.find_end_of_memory (every platform has a device tree with a /memory node now, right?) and fixes some problems with the mpic initialization on newworld powermacs.
