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 ...
