Subject: mm/page_isolation: prefer the node of the source page

Patch series "clean-up the migration target allocation functions", v3.

This patchset clean-up the migration target allocation functions.

Contributions of this patchset are:
1. unify two hugetlb alloc functions. As a result, one is remained.
2. make one external hugetlb alloc function to internal one.
3. unify three functions for migration target allocation.


This patch (of 8):

For locality, it's better to migrate the page to the same node rather than
the node of the current caller's cpu.
