      powerpc: Fix Book-E watchdog timer interval setting · 0a0e9e0c
      Matthias Fuchs authored
      This patch fixes the setting of the Book-E watchdog timer interval setup
      on initialization and by ioctl().
      
      On initialization the period bits have to be masked before setting
      a new period.
      
      In WDIOC_SETTIMEOUT ioctl we have to use the correct mask.

      Kumar Gala authored
      The implemetation of _tlbil_pid() on Freescale Book-E cores needs
      an msync & isync after we flash invalidate the TLBs.  This was causing
      the following oops reported by Sebastian Andrzej Siewior:
