* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  arch/tile: mark "hardwall" device as non-seekable
  asm-generic/stat.h: support 64-bit file time_t for stat()
  arch/tile: don't allow user code to set the PL via ptrace or signal return
  arch/tile: correct double syscall restart for nested signals
  arch/tile: avoid __must_check warning on one strict_strtol check
  arch/tile: bomb raw_local_irq_ to arch_local_irq_
  arch/tile: complete migration to new kmap_atomic scheme
