Subject: [PATCH v2 1/2] efi/libstub/arm64: link stub lib.a conditionally
Date: Thu, 4 Jun 2020 11:20:30 +0900 [thread overview]
Message-ID: <20200604022031.164207-1-masahiroy@kernel.org> (raw)
Since commit 799c43415442 ("kbuild: thin archives make default for
all archs"), core-y is passed to the linker with --whole-archive.
Hence, the whole of stub library is linked to vmlinux.
Use libs-y so that lib.a is passed after --no-whole-archive for
conditional linking.
The unused drivers/firmware/efi/libstub/relocate.o will be dropped
for ARCH=arm64.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

This patch touches under arch/arm64/, but
this is more related to efi.
I am sending this to Ard.
