History
Wei Yang 08994b2467 mm/sparse.c: pass the __highest_present_section_nr + 1 to alloc_func() 
In commit c4e1be9ec1 ("mm, sparsemem: break out of loops early")
__highest_present_section_nr is introduced to reduce the loop counts for
present section.  This is also helpful for usemap and memmap allocation.

This patch uses __highest_present_section_nr + 1 to optimize the loop.
