Hi Mark,

After merging the spi tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/spi/spi-bcm2835.c: In function 'bcm2835_spi_can_dma':
drivers/spi/spi-bcm2835.c:381:7: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  if (((u32)tfr->tx_buf % 4 == 0) && ((u32)tfr->tx_buf % 4 == 0))
       ^

  if (((u32)tfr->tx_buf % 4 == 0) && ((u32)tfr->tx_buf % 4 == 0))

       ^

  if (((u32)tfr->tx_buf % SZ_4K) + tfr->len > SZ_4K) {
                          ^

  if (((u32)tfr->rx_buf % SZ_4K) + tfr->len > SZ_4K) {
       ^

Caused by commit 3ecd37edaa2a ("spi: bcm2835: enable dma modes for
transfers meeting certain conditions").

I have used the spi tree from next-20150511 for today.
