    powerpc: Cleanup memblock usage · 6fbef13c
    Tejun Heo authored
    * early_init_devtree(): Total memory size is aligned to PAGE_SIZE;
      however, alignment isn't enforced if memory_limit is explicitly
      specified.  Simplify the logic and always apply PAGE_SIZE alignment.
    
    * MMU_init(): memblock regions is truncated by directly modifying
      memblock.memory.cnt.  This is incomplete (reserved array is not
      truncated) and unnecessarily low level hindering further memblock
      improvments.  Use memblock_enforce_memory_limit() instead.
    
    * wii_memory_fixups(): Unnecessarily low level direct manipulation of
      memblock regions.  The same result can be achieved using properly
      abstracted operations.  Reimplement using memblock API.
