Subject: [PATCH V7 0/2] powerpc/nodes: Fix issues with memoryless nodes
Date: Thu, 16 Nov 2017 11:24:18 -0600 [thread overview]
Message-ID: <c88f7263-4f99-c13d-c4d2-9fa8f3d59b8f@linux.vnet.ibm.com> (raw)
powerpc/nodes: Ensure enough nodes avail for operations
powerpc/initnodes: Ensure nodes initialized for hotplug
hotplug/cpu: Fix crash with memoryless nodes

Michael Bringmann (3):
powerpc/nodes: Ensure enough nodes avail for operations
powerpc/initnodes: Ensure nodes initialized for hotplug
hotplug/cpu: Fix crash with memoryless nodes
---
Changes in V7:
-- Remove some node initialization/allocation from boot setup
to later in runtime to try to limit memory needs early on
-- Add some needed node initialization to runtime code that maps
CPUs based on VPHN associativity
-- Add error checks and alternate recovery for compile flag
CONFIG_MEMORY_HOTPLUG
-- Add alternate node selection recovery for !CONFIG_MEMORY_HOTPLUG
-- Add initialization for systems that start using nodes before new
CPU brought online.
-- Make function find_cpu_nid() externally visible/usable so that
it may be used from hotplug-cpu.c
