From 89f686b3c5bfcd6d6ce40c6250ee3822e11801d3 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Wed, 25 Nov 2015 02:59:45 -0800 Subject: [PATCH 1/3] kbuild: derive relative path for KBUILD_SRC from CURDIR This enables relocating source and build trees to different roots, provided they stay reachable relative to one another. Useful for builds done within a sandbox where the eventual root is prefixed by some undesirable path component. --- Makefile | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/Makefile b/Makefile index eb18d200a60304..111745f5497d51 100644 --- a/Makefile +++ b/Makefile @@ -143,7 +143,8 @@ $(filter-out _all sub-make $(CURDIR)/Makefile, $(MAKECMDGOALS)) _all: sub-make # Invoke a second make in the output directory, passing relevant variables sub-make: - $(Q)$(MAKE) -C $(KBUILD_OUTPUT) KBUILD_SRC=$(CURDIR) \ + $(Q)$(MAKE) -C $(KBUILD_OUTPUT) \ + KBUILD_SRC=$(shell realpath --relative-to=$(KBUILD_OUTPUT) $(CURDIR)) \ -f $(CURDIR)/Makefile $(filter-out _all sub-make,$(MAKECMDGOALS)) # Leave processing to above invocation of make From 7ac9352a964be3ad2176ba8d50eb5ea77a9097e7 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Fri, 11 Nov 2016 17:28:52 -0800 Subject: [PATCH 2/3] Add arm64 coreos verity hash Signed-off-by: Geoff Levand --- arch/arm64/kernel/efi-header.S | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/arch/arm64/kernel/efi-header.S b/arch/arm64/kernel/efi-header.S index 613fc3000677f7..fdaf86c783329c 100644 --- a/arch/arm64/kernel/efi-header.S +++ b/arch/arm64/kernel/efi-header.S @@ -103,6 +103,11 @@ section_table: .set section_count, (. - section_table) / 40 + /* CoreOS 64 byte verity hash value. */ + .org _head + 512 + .ascii "verity-hash" + .org _head + 512 + 64 + #ifdef CONFIG_DEBUG_EFI /* * The debug table is referenced via its Relative Virtual Address (RVA), From 26c902aba296e8632557b03486d11835c53f06d3 Mon Sep 17 00:00:00 2001 From: David Michael Date: Thu, 8 Feb 2018 21:23:12 -0500 Subject: [PATCH 3/3] tools/objtool/Makefile: Don't fail on fallthrough with new GCCs --- tools/lib/subcmd/Makefile | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tools/lib/subcmd/Makefile b/tools/lib/subcmd/Makefile index 95563b8e1ad743..307652c42a7b6e 100644 --- a/tools/lib/subcmd/Makefile +++ b/tools/lib/subcmd/Makefile @@ -33,6 +33,9 @@ ifneq ($(WERROR),0) CFLAGS += -Werror endif +# Don't fail on fallthrough with newer GCCs. +CFLAGS += -Wno-error=implicit-fallthrough + CFLAGS += -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE CFLAGS += -I$(srctree)/tools/include/
