Subject: [PATCH v2 3/6] efi: stub: move efi_system_table global var into separate object
Date: Tue, 9 Aug 2022 10:09:41 +0200 [thread overview]
Message-ID: <20220809080944.1119654-4-ardb@kernel.org> (raw)
In-Reply-To: <20220809080944.1119654-1-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.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
