Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6:
Blackfin arch: be less noisy when gets a gpio conflict after kernel has booted
Blackfin arch: add RSI's definitions to bf514 and bf516
Blackfin arch: add link-time asserts to make sure on-chip regions dont overflow
Blackfin arch: sport spi needs 6 gpio pins
Blackfin arch: add sport-spi related resource stuff to board file
Blackfin arch: Blacklist Hibernate (PM_SUSPEND_MEM) on BF561 as well
Blackfin arch: Privide BF537-STAMP platform data of ADP5520 Multifunction driver
Blackfin arch: enable the platfrom PATA driver with CF Cards
Blackfin arch: clean up sports header file
Blackfin arch: convert BF5{18,27,48}_FAMILY to CONFIG_BF{51,52,54}x
Blackfin arch: bf51x processors also have 8 timers
Blackfin arch: add a check to make sure only Blackfin GPIOs may generate IRQs
Blackfin arch: update default kernel configuration
Blackfin arch: include linux headers that this one uses definitions from fro sport drivers
