Merge branches 'gpio/merge' and 'spi/merge' of git://git.secretlab.ca/git/linux-2.6 

* 'gpio/merge' of git://git.secretlab.ca/git/linux-2.6:
  gpio: add GPIOF_ values regardless on kconfig settings
  gpio: include linux/gpio.h where needed
  gpio/omap4: Fix missing interrupts during device wakeup due to IOPAD.

* 'spi/merge' of git://git.secretlab.ca/git/linux-2.6:
  spi/bfin_spi: fix handling of default bits per word setting
