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: (74 commits)
  Blackfin serial driver: pending a unique anomaly id, tie the break flood issue to ANOMALY_05000230
  blackfin enable arbitary speed serial setting
  Blackfin arch: Remove cruft - CONFIG_DEBUG_SERIAL_EARLY_INIT and DEBUG_KERNEL_START
  Blackfin arch: fix typo in register name
  Blackfin arch: trim the Blackfin arch MAINTAINERS list
  Blackfin arch: fix bug libstdc++ calling writev with an iovec containing { NULL, 0 } fails on Blackfin
  Blackfin arch: Export strcpy - occasionally get module link failures otherwise
  Blackfin arch: the load address is not safe to point to as a workaround for ANOMALY 05000281
  Blackfin arch: show_mem can not be marked as init, since it is called during OOM condition
  Blackfin arch: flush/inv the correct range when using write back cache and fix bugs find by dmacopy
  Blackfin arch: update kgdb patch
  Blackfin arch: Comply with revised Anomaly Workarounds for BF533 05000311 and BF561 05000323
  Blackfin arch: Print out debug info, as early as possible
  Blackfin arch: Enable earlyprintk earlier - so any error after our interrupt tables are set up will print out
  Blackfin arch: fix endless loop bug when a double fault happens
  Blackfin arch: Initial patch to add earlyprintk support
  Blackfin arch: add TWIx_REGBASE and SPIx_REGBASE to specific CPU header files, use the new REGBASE for board platform resources
  Blackfin arch: modify the insX/outsX and dma_insX/dma_outsX to be compatible with other archs
  Blackfin arch: add more common defines for output sections
  Blackfin arch: cleanup IO and DMA_IO API function definitions according to other arches
