Subject: [PATCH] kbuild: disable header exports for UML in a straightforward way
Date: Thu, 1 Sep 2022 10:12:52 +0900 [thread overview]
Message-ID: <20220901011252.550830-1-masahiroy@kernel.org> (raw)
Previously 'make ARCH=um headers' stopped because of missing
arch/um/include/uapi/asm/Kbuild.
The error is not shown since commit ed102bf2afed ("um: Fix W=1
missing-include-dirs warnings") because UML got
arch/um/include/uapi/asm/Kbuild.
Hard-code the unsupported architecture, so it works like before.
Fixes: ed102bf2afed ("um: Fix W=1 missing-include-dirs warnings")
