[PATCH v3 0/2] mm/mm_init: simplify zone_spanned_pages_in_node()

[Sang-Heon Jeon <ekffu200098@gmail.com>]

Hello,

This series simplifies zone_spanned_pages_in_node(), which adjusts
*zone_start_pfn and *zone_end_pfn before and after calling
adjust_zone_range_for_zone_movable(). The helper adjusts the same two
values, which makes the code harder to follow.

Patch 1 folds adjust_zone_range_for_zone_movable() into the caller,
extracts zone_movable_pfn[nid] into a local variable, and reduces the
indentation level.

Patch 2 removes the clamping to node_end_pfn and moves the check and
the clamping to node_start_pfn into the ZONE_MOVABLE branch, which is
the only place they have an effect. It also merges the two branches
that adjust for zone_movable_pfn[nid].

No functional change.
