Subject: [PATCH AUTOSEL 5.7 40/40] x86/boot: Don't add the EFI stub to targets
Date: Mon, 20 Jul 2020 17:37:15 -0400	[thread overview]
Message-ID: <20200720213715.406997-40-sashal@kernel.org> (raw)
In-Reply-To: <20200720213715.406997-1-sashal@kernel.org>

From: Arvind Sankar <nivedita@alum.mit.edu>

[ Upstream commit da05b143a308bd6a7a444401f9732678ae63fc70 ]

vmlinux-objs-y is added to targets, which currently means that the EFI
stub gets added to the targets as well. It shouldn't be added since it
is built elsewhere.

This confuses Makefile.build which interprets the EFI stub as a target
	$(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a
and will create drivers/firmware/efi/libstub/ underneath
arch/x86/boot/compressed, to hold this supposed target, if building
out-of-tree. [0]

Fix this by pulling the stub out of vmlinux-objs-y into efi-obj-y.

[0] See scripts/Makefile.build near the end:
    # Create directories for object files if they do not exist
