When comparing a pointer, it's clearer to compare it to NULL than to 0.
stram_start = phys_to_virt(0); - kernel_in_stram = (stram_start == 0); + kernel_in_stram = (stram_start == NULL);
stram_start is more like an offset than pointer, IMHO. And 0 is a valid offset. The "==NULL" does not make much sense in this particular case. NULL is usually used when checking for an uninitialized pointer, right?
