Add support for an "archheaders" target. This target can generate
files that need to be installed for user space by "make
headers_install" or "make headers_install_all".In order to support "make headers_install_all", it must be able to run
without the tree having to be configured first.Cc: David Woodhouse

Starting with 4.4, gcc will happily accept -Wno- in the
cc-option test and complain later when compiling a file that has some
other warning. This rather unexpected behavior is intentional as per
http://gcc.gnu.org/PR28322, so work around it by testing for support of
the opposite option (without the no-). Introduce a new Makefile function
cc-disable-warning that does this and update two uses of cc-option in
the toplevel Makefile.Reported-and-tested-by: Stephen Rothwell

There is an increasing amount of header files
shared between individual architectures in asm-generic.
To avoid a lot of dummy wrapper files that just
include the corresponding file in asm-generic provide
some basic support in kbuild for this.With the following patch an architecture can maintain
a list of files in the file arch/$(ARCH)/include/asm/KbuildTo use a generic file just add:
generic-y +=
For each file listed kbuild will generate the necessary
wrapper in arch/$(ARCH)/include/generated/asm.When installing userspace headers a wrapper is likewise created.
The original inspiration for this came from the unicore32
patchset - although a different method is used.The patch includes several improvements from Arnd Bergmann.
Michael Marek contributed Makefile.asm-generic.Remis Baima did an intial implementation along to achive
the same - see https://patchwork.kernel.org/patch/13352/Signed-off-by: Sam Ravnborg

Add a 'W=1' Makefile switch which adds additional checking per build
object.The idea behind this option is targeted at developers who, in the
process of writing their code, want to do the occasionalmake W=1 [target.o]
and let gcc do more extensive code checking for them. Then, they
could eyeball the output for valid gcc warnings about various
bugs/discrepancies which are not reported during the normal build
process.For more background information and a use case, read through this

This patch adds support for linking device tree blob(s) into
vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking
.dtb sections into vmlinux. To maintain compatiblity with the of/fdt
driver code platforms MUST copy the blob to a non-init memory location
before the kernel frees the .init.* sections in the image.Modifies scripts/Makefile.lib to add a kbuild command to
compile DTS files to device tree blobs and a rule to create objects to
wrap the blobs for linking.STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to
create wrapper objects for the dtb in Makefile.lib. The
STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the
STRUCT_ALIGNMENT definition.The DTB's are placed on 32 byte boundries to allow parsing the blob
with driver/of/fdt.c during early boot without having to copy the blob
to get the structure alignment GCC expects.A DTB is linked in by adding the DTB object to the list of objects to
be linked into vmlinux in the archtecture specific Makefile using

Usefull if building for sparc64 userland, because the
sparc and sparc64 userlands use the same 64-bit kernel,
making it impossible to always select the correct userland
architecture for the resulting debian package.Might also be usefull, if you want a i386 userland with a amd64 kernel.
