gaoxu 04e774fb67 dma-remap: use kvmalloc_array/kvfree for larger dma memory remap 
[ Upstream commit 51ff97d54f02b4444dfc42e380ac4c058e12d5dd ]

If dma_direct_alloc() alloc memory in size of 64MB, the inner function
dma_common_contiguous_remap() will allocate 128KB memory by invoking
the function kmalloc_array(). and the kmalloc_array seems to fail to try to
allocate 128KB mem.

Call trace:

work around by doing kvmalloc_array instead.
