Subject: Re: [PATCH 09/14] s390/vdso: Drop unused '-s' flag from KBUILD_AFLAGS_64
Date: Thu, 05 Jan 2023 08:27:44 +0100	[thread overview]
Message-ID: <yt9dbkndh24v.fsf@linux.ibm.com> (raw)
In-Reply-To: <20221228-drop-qunused-arguments-v1-9-658cbc8fc592@kernel.org> (Nathan Chancellor's message of "Wed, 04 Jan 2023 12:54:26 -0700")

Nathan Chancellor <nathan@kernel.org> writes:

> When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it
