[PATCH v4 0/4] mm: clean up names and parameters of memmap_init_xxxx functions

[Baoquan He <bhe@redhat.com>]

This patchset is correcting inappropriate function names of
memmap_init_xxx, and simplify parameters of functions in the code flow
when I tried to fix a regression bug in memmap defer init. 

This is based on the latest next/master.

v3 can be found here:
https://lore.kernel.org/linux-mm/20210105074708.18483-1-bhe@redhat.com/

v3->v4:
 - Rebased patch 1, 2 on top of Mike's below new patch.
   [PATCH v3 0/2] mm: fix initialization of struct page for holes in  memory layout
  
 - Move the code of renaming function parameter 'range_start_pfn' and local
   variable 'range_end_pfn' of memmap_init() from patch 1 to patch 2
   according to David's comment.

 - Use the reverse Christmas tree style to reorder the local variables
   in memmap_init_zone() in patch 2 accodrding to David's comment.
