[PATCH 09/49] memblock: Introduce default allocation limit and use it to replace explicit ones
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> This introduce memblock.current_limit which is used to limit allocations from memblock_alloc() or memblock_alloc_base(..., MEMBLOCK_ALLOC_ACCESSIBLE). The old MEMBLOCK_ALLOC_ANYWHERE changes value from 0 to ~(u64)0 and can still be used with memblock_alloc... 19 Jul 2010 20:10
