We need to include <linux/vmalloc.h> in order for MIPS to find vmap(), as it doesn't otherwise get included there.
Without this patch, one can hit the following build error: drivers/dma-buf/heaps/cma_heap.c: In function 'cma_heap_do_vmap': drivers/dma-buf/heaps/cma_heap.c:195:10: error: implicit declaration of function 'vmap'
