Hi, It seems generating a coredump on an at91rm9200 with kernels 3.4 and 3.5 causes an oops. The function get_dump_page calls vivt_flush_cache_page which tests if the current cpu belongs to mm_cpumask(vma->vm_mm), but vma->vm_mm is NULL for the vector page. Setting gate_vma.vm_mm to &init_mm seems to avoid the issue, but I am not sure this is the right thing to do.
