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: (28 commits)
  Blackfin arch: SPI_MMC is now mainlined MMC_SPI
  Blackfin arch: disable legacy /proc/scsi/ support by default
  Blackfin arch: remove duplicated ANOMALY_05000448 ifdef check
  Blackfin arch: add stubs for anomalies 447 and 448
  Blackfin arch: cleanup bfin_sport.h header and export it to userspace
  Blackfin arch: fix bug - gdb signull case make trunk kernel panic frequently
  Blackfin arch: remove spurious dash when dcache is off
  Blackfin arch: mark init_pda as __init as only __init funcs all it
  Blackfin arch: fix bug - On bf548-ezkit, ethernet fails to work after wakeup from "mem"
  Blackfin arch: Random read/write errors are a bad thing
  Blackfin arch: update default kernel config, select KSZ8893M driver for BF518
  Blackfin arch: Fix bug - KGDB single step into the middle of a 4 bytes instruction on bf561 after soft bp is hit
  Blackfin arch: Fix bug - make ksz8893m driver available when bfin_mac is enabled
  Blackfin arch: make sure people do not set the kernel load address too high
  Blackfin arch: fix bug - The SPORT_HYS bit is not set for BF561 0.5
  Blackfin arch: update anomaly sheets to match latest public info
  Blackfin arch: Fix BUG - kernel fails to build in pm.c when allow wakeup fromi standby by GPIO
  Blackfin arch: PM_BFIN_WAKE_GP: update help
  Blackfin arch: fix bug - kgdb fails to continue after setting breakpoint on bf561-ezkit kernel with smp patch
  Blackfin arch: Enable Write Back Cache on all Blackfin Boards
