Subject: [PATCH] x86/um/vdso: Drop implicit common-page-size linker flag
Date: Mon, 10 Dec 2018 14:27:16 -0800 [thread overview]
Message-ID: <20181210222718.19926-1-ndesaulniers@google.com> (raw)
GNU linker's -z common-page-size's default value is based on the target
architecture. arch/x86/entry/vdso/Makefile sets it to the architecture
default, which is implicit and redundant. Drop it.
