[PATCH] powerpc: Always panic if lmb_alloc() fails
Currently most callers of lmb_alloc() don't check if it worked or not, if it ever does weird bad things will probably happen. The few callers who do check just panic or BUG_ON. So make lmb_alloc() panic internally, to catch bugs at the source. The few callers who did check the result no longer need to. The only caller that did anything interesting with the return result was careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic automatically, a little messy, but passable.
