[PATCH 03/11] memblock: Introduce lowest limit in memblock.

2013-08-27 Thread Tang Chen
The current memblock allocates memory from high address to low. And it has a highest limit. The next coming patches will improve memblock to be able to allocate memory from low address to high. So we need a lowest limit. Introduce current_limit_low to memblock. When users specify start address
