Subject: [RFC PATCH v3 01/24] NUMA: Make number of NUMA nodes configurable
Date: Tue, 18 Jul 2017 17:11:23 +0530 [thread overview]
Message-ID: <1500378106-2620-2-git-send-email-vijay.kilari@gmail.com> (raw)
In-Reply-To: <1500378106-2620-1-git-send-email-vijay.kilari@gmail.com>
From: Vijaya Kumar K <Vijaya.Kumar@cavium.com>
Introduce NR_NODES config option to specify number
of NUMA nodes supported. By default value is set at
64 for x86 and 8 for arm. Dropped NODES_SHIFT macro.
Also move NR_NODE_MEMBLKS from asm-x86/acpi.h to xen/numa.h
