Some systems (e.g. Hyper-V guests) have all their memory marked as hotpluggable in SRAT. acpi_numa_memory_affinity_init(), however, ignores all such regions when !CONFIG_MEMORY_HOTPLUG and this is unfortunate as memory affinity (NUMA) information gets lost. 'Hot Pluggable' flag in SRAT only means that "system hardware supports hot-add and hot-remove of this memory region", it doesn't prevent memory from being cold-plugged there. Ignore 'Hot Pluggable' bit instead of skipping the whole memory affinity information when !CONFIG_MEMORY_HOTPLUG. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: Rafael J.

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.
