From ad08fd494bf00c03ae372e0bbd9cefa37bf608d6 Mon Sep 17 00:00:00 2001 From: Steve Capper Date: Mon, 16 Mar 2015 09:30:39 +0000 Subject: [PATCH] arm64: Adjust EFI libstub object include logic Commit f4f75ad5 ("efi: efistub: Convert into static library") introduced a static library for EFI stub, libstub. The EFI libstub directory is referenced by the kernel build system via a obj subdirectory rule in: drivers/firmware/efi/Makefile Unfortunately, arm64 also references the EFI libstub via: libs-$(CONFIG_EFI_STUB) += drivers/firmware/efi/libstub/ If we're unlucky, the kernel build system can enter libstub via two simultaneous threads resulting in build failures such as: fixdep: error opening depfile: drivers/firmware/efi/libstub/.efi-stub-helper.o.d: No such file or directory scripts/Makefile.build:257: recipe for target 'drivers/firmware/efi/libstub/efi-stub-helper.o' failed make[1]: *** [drivers/firmware/efi/libstub/efi-stub-helper.o] Error 2 Makefile:939: recipe for target 'drivers/firmware/efi/libstub' failed make: *** [drivers/firmware/efi/libstub] Error 2 make: *** Waiting for unfinished jobs.... This patch adjusts the arm64 Makefile to reference the compiled library explicitly (as is currently done in x86), rather than the directory.
