gaoxu 4503b78fe6 dma-remap: use kvmalloc_array/kvfree for larger dma memory remap
[ Upstream commit 51ff97d54f ]

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.

work around by doing kvmalloc_array instead.
