Yunfeng Ye 0ac398b171 mm: support memblock alloc on the exact node for sparse_buffer_init()
sparse_buffer_init() use memblock_alloc_try_nid_raw() to allocate memory
for page management structure, if memory allocation fails from specified
node, it will fall back to allocate from other nodes.

Normally, the page management structure will not exceed 2% of the total
memory, but a large continuous block of allocation is needed.  In most
cases, memory allocation from the specified node will succeed, but a
node memory become highly fragmented will fail.  we expect to allocate
memory base section rather than by allocating a large block of memory
from other NUMA nodes

Add memblock_alloc_exact_nid_raw() for this situation, which allocate
boot memory block on the exact node.  If a large contiguous block memory
allocate fail in sparse_buffer_init(), it will fall back to allocate
small block memory base section.
