Hi Mashiro,

	commit 2b50f7ab63685cd247e32ad321f7338ed130d3d5
	Author: Masahiro Yamada <yamada.masahiro@socionext.com>
	kbuild: add workaround for Debian make-kpkg

seems to prevent the use of GNUmakefile wrappers to set the ARCH and
CROSS_COMPILE make variables.  With this commit, I now see:

	make: Entering directory '/data/fs/linux-fs'
	Makefile:39: Do not include top Makefile of Linux Kernel
	***
	*** Configuration file ".config" not found!
	***
	*** Please run some configurator (e.g. "make oldconfig" or
	*** "make menuconfig" or "make xconfig").
	***
	Makefile:605: include/config/auto.conf: No such file or directory
	make: *** No rule to make target '.config', needed by 'include/config/auto.conf'.  Stop.
	make: Leaving directory '/data/fs/linux-fs'

Do you have a suggestion as to how to work around this?  Here's a sample
GNUmakefile content:

	CROSS_COMPILE	:= x86_64-linux-gnu-
	ARCH		:= x86_64
	MFLAGS		+= CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH)
	export CROSS_COMPILE
	export ARCH
	include Makefile

David

I think the following will work.
(code was taken from scripts/mkmakefile)



------------------(GNUmakefile BEGIN)-------------------
CROSS_COMPILE   := x86_64-linux-gnu-
ARCH            := x86_64
MFLAGS          += CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH)
export CROSS_COMPILE
export ARCH

ifeq ("$(origin V)", "command line")
VERBOSE := $(V)
endif
ifneq ($(VERBOSE),1)
Q := @
endif

MAKEFLAGS += --no-print-directory

.PHONY: __sub-make $(MAKECMDGOALS)

__sub-make:
        $(Q)$(MAKE) -f Makefile $(MAKECMDGOALS)

$(filter-out __sub-make, $(MAKECMDGOALS)): __sub-make
        @:
------------------(GNUmakefile END)-------------------



Having said that, the previous cheesy workaround sucks.

How about this patch?
https://patchwork.kernel.org/patch/10858809/

I hope you will be able to wrap the top Makefile again.

That works for me.
