Subject: [PATCH 28/33] efi: Kill __efistub_global
Date: Fri, 24 Apr 2020 15:05:26 +0200 [thread overview]
Message-ID: <20200424130531.30518-29-ardb@kernel.org> (raw)
In-Reply-To: <20200424130531.30518-1-ardb@kernel.org>
From: Arvind Sankar <nivedita@alum.mit.edu>
Now that both arm and x86 are using the linker script to place the EFI
stub's global variables in the correct section, remove __efistub_global.
