      A small fix for the SSI driver and a fix for system shutdown with modern
      devices.  Most of the modern devices will never get shut down normally
      with a visible kernel log as the systems they're in tend not to shut
      down often and when they do it's usually in form factors that don't have
      a user visible console.

      memblock: Fix size aligning of memblock_alloc_base_nid() · 847854f5
      Tejun Heo authored
      memblock allocator aligns @size to @align to reduce the amount
      of fragmentation.  Commit:
      
       7bd0b0f0 ("memblock: Reimplement memblock allocation using reverse free area iterator")
      
      Broke it by incorrectly relocating @size aligning to
      memblock_find_in_range_node().  As the aligned size is not
      propagated back to memblock_alloc_base_nid(), the actually
      reserved size isn't aligned.
      
      While this increases memory use for memblock reserved array,
      this shouldn't cause any critical failure; however, it seems
      that the size aligning was hiding a use-beyond-allocation bug in
      sparc64 and losing the aligning causes boot failure.
      
      The underlying problem is currently being debugged but this is a
      proper fix in itself, it's already pretty late in -rc cycle for
      boot failures and reverting the change for debugging isn't
      difficult. Restore the size aligning moving it to
      memblock_alloc_base_nid().

      virtio: balloon: leak / fill balloon across S4 · 4eb05d56
      Amit Shah authored
      commit e562966d added support for S4 to
      the balloon driver.  The freeze function did nothing to free the pages,
      since reclaiming the pages from the host to immediately give them back
      (if S4 was successful) seemed wasteful.  Also, if S4 wasn't successful,
      the guest would have to re-fill the balloon.  On restore, the pages were
      supposed to be marked freed and the free page counters were incremented
      to reflect the balloon was totally deflated.
      
      However, this wasn't done right.  The pages that were earlier taken away
      from the guest during a balloon inflation operation were just shown as
      used pages after a successful restore from S4.  Just a fancy way of
      leaking lots of memory.
      
      Instead of trying that, just leak the balloon on freeze and fill it on
      restore/thaw paths.  This works properly now.  The optimisation to not
      leak can be added later on after a bit of refactoring of the code.
