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

xtensa and arm have asked for a possibility to export headers
and locate them in a specific directory when exported.
Introduce destiantion-y to support this.This patch in additiona adds some limited
documentation for the variables used for exported headers.Signed-off-by: Sam Ravnborg

We see some header files that are selected dependent on
the actual architecture so force a reinstallation
of all header files when the arch changes.
This slows down "make headers_check_all" but then
we better reflect reality.Signed-off-by: Sam Ravnborg

Move the core functionality of headers_install
and headers_check to two small perl scripts.
The makefile is adapted to use the perl scrip and
changed to operate on all files in a directory.
So if one file is changed then all files in the
directory is processed.perl were chosen for the helper scripts because this
is pure text processing which perl is good at and
especially the headers_check.pl script are expected to
see changes / new checks implmented.The speed is ~300% faster on this box.
And the output generated to the screen is now down to
two lines per directory (one for install, one for check)
so it is easier to scroll back after a kernel build.The perl scripts has been brought to sanity by patient
feedback from: Vegard NossumSigned-off-by: Sam Ravnborg

Move it to the top-level file to decide if we install/check
the generic headers or the arch specific headers.This revealed a long standing bug where "make headers_check_all"
relied on the files in asm/ for the current architecture.
So make headers_check_all is now broken by this commit.In addition:
o add a simpler way to detect if an arch support
exporting header files.o add 'set -e;' so we error out early if
make headers_check_all fails.o add sparc64 and cris to arch we do not process
in make headers_*_all because:sparc64 - use sparc to export headers
cris - is know seriously brokenIncludes suggestions from: David Woodhouse

unifdef utility is fast enough to warrant that we always
run the scripts through unifdef.This patch runs all headers listed with header-y and unifdef-y
through unifdef.
Next step is to drop unifdef-y in all Kbuild files and
that can now be done in smaller steps.Signed-off-by: Sam Ravnborg

The sed expression used at the moment in scripts/Makefile.headersinst
relies on the (handy) GNU extension where you can escape ERE's in an
otherwise BRE without using the GNU -r option. The following patch
replaces this "\+" usage with a functionally equivalent POSIX BRE compliant
"\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386
targets.Stupid whiny OS X users and their crappy sed ;)

A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of
files all of which are using the same #ifdef guard, "__ASM_STUB_" with no
postfix. So the second and later asm files #included in the same C file
(often through standard headers like ioctl.h) yields no symbols.Strangeness with the Ubuntu 'tell me if I support something that's not
explcitly mentioned in POSIX, and I'll strip it out' shell, I believe.We don't need the 'export' but we do need a semicolon at the end of the

This should make it stop immediately after printing the _helpful_ error

less obvious.Now I get this...

We generate an which includes either or
as appropriate. But we were doing this dependent on
whether the file in question existed in the _unexported_ tree, not the
exported tree. So if a file was exported to userspace in one asm- directory
but not the other, the generated file in asm/ was incorrect.This only changed the failure mode if it _was_ included from a nice #error to
a less explicable #include failure -- but it also gave false errors in 'make
headers_check' output. Fix it by looking in the right place instead.Signed-off-by: David Woodhouse

Based on the 'headers_install' target, this performs a basic sanity check
on the exported headers -- so far only checking that they do not include
any other headers which aren't selected for import, but easily extendable.Signed-off-by: David Woodhouse

This adds a make target which exports a subset of headers which contain
definitions which are useful for system libraries and tools. It uses the
BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses
sed to remove markers like __user.Based on an original implementation by Arnd Bergmann
