Baoquan He 4027149abd mm/sparse.c: allocate memmap preferring the given node
When allocating memmap for hot added memory with the classic sparse, the
specified 'nid' is ignored in populate_section_memmap().

While in allocating memmap for the classic sparse during boot, the node
given by 'nid' is preferred.  And VMEMMAP prefers the node of 'nid' in
both boot stage and memory hot adding.  So seems no reason to not respect
the node of 'nid' for the classic sparse when hot adding memory.

Use kvmalloc_node instead to use the passed in 'nid'.

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 Restructured Text 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.
