From 5f51c5d0e905608ba7be126737f7c84a793ae1aa Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 12 Sep 2023 09:00:52 +0000 Subject: x86/efi: Drop EFI stub .bss from .data section Now that the EFI stub always zero inits its BSS section upon entry, there is no longer a need to place the BSS symbols carried by the stub into the .data section.
