Huang Shijie 0ff76a920e mtd: gpmi: add sanity check when mapping DMA for read_buf/write_buf ... The buffer pointer passed from the upper layer may points to a buffer in the stack or a buffer allocated by vmalloc, and etc.. This patch adds more sanity check to this buffer. After this patch, if we meet a buffer which is allocated by vmalloc or a buffer in the stack, we will use our own DMA buffer @data_buffer_dma to do the DMA operations. If the buffer is not the cases above, we will map it for DMA operations directly.
