Song Hu ca30ac479e mm/page_owner: simplify zone iteration logic in init_early_allocated_pages()
The current implementation uses nested loops: first iterating over all
online nodes, then over zones within each node.  This can be simplified by
using the for_each_populated_zone() macro which directly iterates through
all populated zones.

This change:
1. Removes the intermediate init_zones_in_node() function
2. Simplifies init_early_allocated_pages() to use direct zone iteration
3. Updates init_pages_in_zone() to take only zone parameter and access
   node_id via zone->zone_pgdat

The functionality remains identical, but the code is cleaner and more
maintainable.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
