2008-07-25kbuild: prepare headers_* for arch/$ARCH/includeSam Ravnborg1-0/+41
Factor out the headers_*_all support to a seperate shell script and add support for arch specific header files can be located in either arch/$ARCH/include/asm or include/asm-$ARCH/ In "make help" always display the headers_* targets. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-07-25kbuild: install all headers when arch is changedSam Ravnborg2-8/+12
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 <sam@ravnborg.org>
2008-07-25kbuild: optimize headers_* targetsSam Ravnborg4-92/+161
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 Nossum <vegard.nossum@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-07-25kbuild: only one call for include/ in make headers_*Sam Ravnborg1-9/+0
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 broken Includes suggestions from: David Woodhouse <dwmw2@infradead.org>.

2008-07-25kbuild: drop support of ALTARCH for headers_*Sam Ravnborg1-75/+9

2008-07-25kbuild: always unifdef files in headers_install*Sam Ravnborg1-19/+10
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.

2008-07-25find dynamic stack allocations in checkstack.plEric Sandeen1-1/+23
Currently, checkstack.pl only looks for fixed subtractions from the stack pointer. However, things like this: void function(int size) { char stackbuster[size << 2]; ... are certainly worth pointing out, I think. This could perhaps be done more cleanly, and the following patch only adds "dynamic" REs for x86 and x86_64, but it works: 0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax) 0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax) 0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax) 0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax) ...

Trying to compile the v850 port brings many compile errors, one of them exists since at least kernel 2.6.19. There also seems to be noone willing to bring this port back into a usable state. This patch therefore removes the v850 port.

2008-06-12kbuild: ignore powerpc specific symbols in modpostSam Ravnborg1-5/+20
Kumar Gala <galak@kernel.crashing.org> wrote: We have a case in powerpc in which we want to link some library routines with all module objects. The routines are intended for handling out-of-line function call register save/restore so having them as EXPORT_SYMBOL() is counter productive (we do also need to link the same "library" code into the kernel). Without this patch a powerpc build would error out and fail to build modules with the added register save/restore module. There were two obvious solutions: 1) To link the .o file before the modpost stage 2) To ignore the symbols in modpost Option 1) was ruled out because we do not have any separate linking stage for single file modules. This patch implements option 2 - and do so only for powerpc.
