* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  arch/tile: check kmalloc() result
  arch/tile: catch up on various minor cleanups.
  arch/tile: avoid erroneous error return for PTRACE_POKEUSR.
  tile: set ARCH_KMALLOC_MINALIGN
  tile: remove homegrown L1_CACHE_ALIGN macro
  arch/tile: Miscellaneous cleanup changes.
  arch/tile: Split the icache flush code off to a generic <arch> header.
  arch/tile: Fix bug in support for atomic64_xx() ops.
  arch/tile: Shrink the tile-opcode files considerably.
  arch/tile: Add driver to enable access to the user dynamic network.
  arch/tile: Enable more sophisticated IRQ model for 32-bit chips.
  Move list types from <linux/list.h> to <linux/types.h>.
  Add wait4() back to the set of <asm-generic/unistd.h> syscalls.
  Revert adding some arch-specific signal syscalls to <linux/syscalls.h>.
  arch/tile: Do not use GFP_KERNEL for dma_alloc_coherent(). Feedback from fujita.tomonori@lab.ntt.co.jp.
  arch/tile: core support for Tilera 32-bit chips.
  Fix up the "generic" unistd.h ABI to be more useful.
