| Could you try to avoid consuming another GFP flag? __GFP_BITS_SHIFT is

| mask. This is pretty limited right now and so the patch does work.

| But maybe we can combine some flags __GFP_NOFAIL | __GFP_REPEAT or so?
| 
| __GFP_NOFAIL already has the semantics that the allocation cannot fail and
| that the page allocator must never return NULL.

| 

As I see page allocator already quite modified in -mm tree.
Christoph will kmalloc with (__GFP_NOFAIL | __GFP_REPEAT)
inform us on exhausted memory? Or we just stuck with blank
screen instead (not blank actually but with previous messages)?
