Subject: [PATCH] docs: kernel-parameters: mark numa=off is supported by a bundle of architectures
Date: Mon, 24 May 2021 17:17:15 +1200 [thread overview]
Message-ID: <20210524051715.13604-1-song.bao.hua@hisilicon.com> (raw)
risc-v and arm64 support numa=off by common arch_numa_init()
in drivers/base/arch_numa.c. x86, ppc, mips, sparc support it
by arch-level early_param.
numa=off is widely used in linux distributions. it is better
to document it.
