Subject: [PATCH v5 4/8] efi/libstub: move efi_system_table global var into separate object
Date: Sat, 10 Sep 2022 10:11:48 +0200 [thread overview]
Message-ID: <20220910081152.2238369-5-ardb@kernel.org> (raw)
In-Reply-To: <20220910081152.2238369-1-ardb@kernel.org>
To avoid pulling in the wrong object when using the libstub static
library to build the decompressor, define efi_system_table in a separate
compilation unit.
