Then rebase the v4 patches on top of it. 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.
