[PATCH 0/3] CMA: Handle the issues of aggressively allocate the

[Hui Zhu <zhuhui@xiaomi.com>]

I tried the Joonsoo's CMA patches [1] in my part and found that they works
better than mine [2] about handle LRU and other issues even if they
don't shrink the memory before cma_alloc.  So I began to test it in my
part.
But my colleague Weixing found some issues around it.  So we make 2 patches to
handle the issues.
And I merged cma_alloc_counter from [2] to cma_alloc work better.

This patchset is based on aa39477b5692611b91ac9455ae588738852b3f60 and [1].
