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: (54 commits)
MAINTIANERS: just use Mike gmail e-mail for contact and pawn the serial driver off onto Sonic
[Blackfin] arch: remove old I2C BF54x porting.
[Blackfin] arch: Add the semtimedop syscall. Upstream uClibc doesn't compile without it.
[Blackfin] arch: fix bug kernel boot message: memory information is not reasonable
[Blackfin] arch: use common flash driver to setup partitions rather than the bf5xx-flash driver
[Blackfin] arch: Fix bug - kernel build with Debug option enabled fails to boot up
[Blackfin] arch: Fix bug Only RTC interrupt can wake up deeper sleep core.
[Blackfin] arch: Add proper SW System Reset delay sequence
[Blackfin] arch: Update copyright date
[Blackfin] arch: GPIO API cleanup and anomaly update
[Blackfin] arch: Fix BUG gpio_direction_output API is not compatitable with GENERIC_GPIO API interface
[Blackfin] arch: Initial checkin of the memory protection support.
[Blackfin] arch: set_bfin_dma_config shouldnt set SYNC or RESTART by default - add argument or option
[Blackfin] arch: Add some comments - fix semicolons
[Blackfin] arch: move all code related to CPLB handling into a new subdirectory under kernel/
[Blackfin] arch: print out list of modules if kernel is crashing and tell people if the kernel is tainted
[Blackfin] arch: enable generic GPIO based I2C driver in STAMP-BF533, EZKIT-BF533 and EZKIT-BF561 boards
[Blackfin] arch: Don't oops_in_progress if single step is comming from the kernel
[Blackfin] arch: Fix BUG - kernel sometimes would stuck with KEYBOARD_GPIO on
[Blackfin] arch: update to latest anomaly sheets
