  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
