Hi Chris,

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

drivers/mmc/host/tmio_mmc_pio.c: In function 'sd_ctrl_read16_rep':
drivers/mmc/host/tmio_mmc_pio.c:56: error: implicit declaration of function 'readsw'
drivers/mmc/host/tmio_mmc_pio.c: In function 'sd_ctrl_write16_rep':
drivers/mmc/host/tmio_mmc_pio.c:73: error: implicit declaration of function 'writesw'

Presumably caused by commit b6147490e6aa ("mmc: tmio: split core
functionality, DMA and MFD glue").

I have used the mmc tree from next-20110325 for tdoay.

Stephen, please verify, that this fixes your problem.
