Subject: [PATCH v5 6/6] hw/arm/virt: Drop superfluous checks against highmem
Date: Fri, 14 Jan 2022 14:07:41 +0000	[thread overview]
Message-ID: <20220114140741.1358263-7-maz@kernel.org> (raw)
In-Reply-To: <20220114140741.1358263-1-maz@kernel.org>

Now that the devices present in the extended memory map are checked
against the available PA space and disabled when they don't fit,
there is no need to keep the same checks against highmem, as
highmem really is a shortcut for the PA space being 32bit.
