spi: Avoid mapping non kmalloc'd buffers for DMA Flash filesystems like JFFS2, UBIFS can provide vmalloc'd or kmap'd buffers that cannot be mapped using dma_map_sg() and can potentially be in memory region above 32bit addressable region(ie buffers belonging to memory region backed by LPAE) of DMA, don't map such buffers for DMA. SPI controller drivers may have to use bounce buffers/memcpy() in such cases. Signed-off-by: Vignesh R <vigneshr@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
