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: (35 commits)
  Blackfin Serial Driver: Fix bug - Only insert UART rx char in timer task.
  Blackfin Serial Driver: Fix bug - update tx dma buffer tail before wake up processes.
  Blackfin Serial Driver: Fix bug - Increase buffer tail immediately before starting tx dma.
  [Blackfin] serial driver: Add flow control support to bf54x
  [Blackfin] serial driver: Fix bug Poll RTS/CTS status in DMA mode as well
  [Blackfin] serial driver: ADSP-BF52x arch/mach support
  [Blackfin] serial driver: use simpler comment headers and strip out information that is maintained in the scm's log
  [Blackfin] serial driver: rework break flood anomaly handling to be more robust/realistic about what we can actually work around
  [Blackfin] serial driver: fix bug - cache the bits of the LSR on systems where the LSR is read-to-clear
  [Blackfin] serial driver: fix bug - should not wait for the TFI bit, just clear it when tx stop.
  [Blackfin] serial driver: Fix bug serial driver in DMA mode spams history to console on shell restart
  [Blackfin] serial driver: Fix bug Free rx dma buffer in shutdown.
  [Blackfin] serial driver: Clean up UART DMA code.
  Blackfin Serial driver: Fix bug - serial driver in PIO mode cant handle input very quickly
  [Blackfin] arch: kill section mismatch warnings
  [Blackfin] arch: handle the most common L1 shrinkage case (L1 does not exist for a part) so that any parts labeled for L1 instead get placed into external memory sections
  [Blackfin] arch: add bfin_clear_PPIx_STATUS() helper funcs like we have for other parts
  [Blackfin] arch: make sure we have proper description/copyright/license lines
  [Blackfin] arch: Fix CONFIG_PM support for BF561
  [Blackfin] arch: Remove DPMC char driver option
