Subject: [PATCH v2 25/25] docs: move numa=fake description to kernel-parameters.txt
Date: Tue, 23 Jul 2024 09:41:56 +0300	[thread overview]
Message-ID: <20240723064156.4009477-26-rppt@kernel.org> (raw)
In-Reply-To: <20240723064156.4009477-1-rppt@kernel.org>

From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>

NUMA emulation can be now enabled on arm64 and riscv in addition to x86.

Move description of numa=fake parameters from x86 documentation of
admin-guide/kernel-parameters.txt

Suggested-by: Zi Yan <ziy@nvidia.com>
Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org>
