Subject: [PATCH AUTOSEL 6.4 17/25] misc: open-dice: make OPEN_DICE depend on HAS_IOMEM
Date: Fri, 8 Sep 2023 20:37:05 -0400 [thread overview]
Message-ID: <20230909003715.3579761-17-sashal@kernel.org> (raw)
In-Reply-To: <20230909003715.3579761-1-sashal@kernel.org>
From: Baoquan He <bhe@redhat.com>
[ Upstream commit aefc8b57af7787c80686e49a5841e9289cb11f53 ]
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.
Here let OPEN_DICE depend on HAS_IOMEM so that it won't be built
to cause below compiling error if PCI is unset:
------
ERROR: modpost: "devm_memremap" [drivers/misc/open-dice.ko] undefined!
ERROR: modpost: "devm_memunmap" [drivers/misc/open-dice.ko] undefined!
------
