      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().
