    treewide: add checks for the return value of memblock_alloc*() · 8a7f97b9
    Mike Rapoport authored
    Add check for the return value of memblock_alloc*() functions and call
    panic() in case of error.  The panic message repeats the one used by
    panicing memblock allocators with adjustment of parameters to include
    only relevant ones.
    
    The replacement was mostly automated with semantic patches like the one
    below with manual massaging of format strings.
    
      @@
      expression ptr, size, align;

      ptr = memblock_alloc(size, align);
      + if (!ptr)
      + 	panic("%s: Failed to allocate %lu bytes align=0x%lx\n", __func__, size, align);
