MIPS: Octeon: Select CONFIG_HOLES_IN_ZONE
Current Octeon systems do in fact have holes in their memory zones. We need to select HOLES_IN_ZONE. If we do not, some memory configurations will result in crashes at boot time like this: . . . CPU 6 Unable to handle kernel paging request at virtual address 0000000000700000, epc == ffffffff8118fe00, ra == ffffffff8118fe9c Oops[#1]: Cpu 6 . . . ... Call Trace: [<ffffffff8118fe00>] setup_per_zone_wmarks+0x1b0/0x338 [<ffffffff815cd738>] init_per_zone_wmark_min+0x64/0xd0 [<ffffffff81100438>] do_one_initcall+0x38/0x160 . . .
