commit e8f1c8118f7693be20eab2abcb86d16d12729ba0 Author: Wei Chen <wei.chen@xxxxxxx> AuthorDate: Fri Jun 10 13:53:13 2022 +0800 Commit: Julien Grall <jgrall@xxxxxxxxxx> CommitDate: Fri Jun 17 09:36:12 2022 +0100 xen/arm: use !CONFIG_NUMA to keep fake NUMA API We have introduced CONFIG_NUMA in a previous patch. And this option is enabled only on x86 at the current stage. In a follow up patch, we will enable this option for Arm. But we still want users to be able to disable the CONFIG_NUMA via Kconfig. In this case, keep the fake NUMA API, will make Arm code still able to work with NUMA aware memory allocation and scheduler.
