Merge tag 'for-linus' of git://github.com/openrisc/linux

Pull OpenRISC updates from Stafford Horne:
 "A few patches all over the place during this cycle, mostly bug and
  sparse warning fixes for OpenRISC, but a few enhancements too. Note,
  there are 2 non OpenRISC specific fixups.

  Non OpenRISC fixes:

   - In init we need to align the init_task correctly to fix an issue
     with MUTEX_FLAGS, reviewed by Peter Z. No one picked this up so I
     kept it on my tree.

   - In asm-generic/io.h I fixed up some sparse warnings, OK'd by Arnd.
     Arnd asked to merge it via my tree.

  OpenRISC fixes:

   - Many fixes for OpenRISC sprase warnings.

   - Add support OpenRISC SMP tlb flushing rather than always flushing
     the entire TLB on every CPU.

   - Fix bug when dumping stack via /proc/xxx/stack of user threads"
