Kumar Gala b41d6fee37 powerpc/fsl-booke: Fix synchronization bug w/local tlb invalidates 
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:

  VFS: Mounted root (nfs filesystem) readonly.
  Freeing unused kernel memory: 148k init
  BUG: sleeping function called from invalid context at /home/bigeasy/git/linux-2.6-powerpc/mm/mmap.c:234
  in_atomic():1, irqs_disabled():0
