proc_oom_score(task) has a reference to task_struct, but that is all. If this task was already released before we take tasklist_lock - we can't use task->group_leader, it points to nowhere - it is not safe to call badness() even if this task is ->group_leader, has_intersects_mems_allowed() assumes it is safe to iterate over ->thread_group list. - even worse, badness() can hit ->signal == NULL Add the pid_alive() check to ensure __unhash_process() was not called. Also, use "task" instead of task->group_leader. badness() should return the same result for any sub-thread. Currently this is not true, but this should be changed anyway.

When the system has no lmb bram, main memory should be start from zero because of microblaze vectors. DTS fragment could look like: DDR2_SDRAM: memory@0 { device_type = "memory"; reg = < 0x0 0x10000000 >; } ; Then you have to setup CONFIG_KERNEL_BASE_ADDR=0 which caused that kernel physical start address will be zero. On reset vector place will be jump to 0x100 and on 0x100 starts kernel text. You have to solve how to load the kernel before cpu starts. Tested with XMD.
