[POWERPC] Add memory regions to the kcore list for 32-bit machines
The entries are only 32-bit, so restrict the virtual address to stay below 0xffff_ffff. With KERNELBASE set to 0xc000_0000, this in effect restricts access to the first 1GB of real memory. Make setup_kcore conditional on CONFIG_PROC_KCORE for both 32/64. Signed-off-by: Ed Swarthout <Ed.Swarthout@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
