I have some questions about the memory map on linux on 8xx and ppc 1)Some area eg BCSR mapped below KERNELBASE,is this safe? I check some process's vm area,it does not fall in this area,will it be unsafe under some circumstances? 2)I read mapin_ram() in mm/init.c ,found that phys mem is also mapped both by bat and page table ,what is this for? Can someone help me? ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
