Helge Deller 9372450cc2 parisc: add kernel stack overflow check ... Add the CONFIG_DEBUG_STACKOVERFLOW config option to enable checks to detect kernel stack overflows. Stack overflows can not be detected reliable since we do not want to introduce too much overhead. Instead, during irq processing in do_cpu_irq_mask() we check kernel stack usage of the interrupted kernel process. Kernel threads can be easily detected by checking the value of space register 7 (sr7) which is zero when running inside the kernel. Since THREAD_SIZE is 16k and PAGE_SIZE is 4k, reduce the alignment of the init thread to the lower value (PAGE_SIZE) in the kernel vmlinux.ld.S linker script.
