Vlastimil Babka e2d18cbf17 mm, slab: restore NUMA policy support for large kmalloc
The slab allocator observes the task's NUMA policy in various places
such as allocating slab pages. Large kmalloc() allocations used to do
that too, until an unintended change by c4cab55752 ("mm/slab_common:
cleanup kmalloc_large()") resulted in ignoring mempolicy and just
preferring the local node. Restore the NUMA policy support.

Fixes: c4cab55752 ("mm/slab_common: cleanup kmalloc_large()")

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.
