* kbuild: fix make TAGS (for emacs use)Sam Ravnborg2005-07-28
| | | | | | | | | From: bongiojp@clarkson.edu <Jeremy Bongio> make TAGS does not make source code tags for emacs. It instead returns an error than "etags -" isn't valid. The problem is easily remedied. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: silence mystery messageSam Ravnborg2005-07-27
| | | | | | | | | | | | | | During last phase of the build the following message were displayed: /bin/sh: +@: command not found This message appears due to slightly changed semantics of cmd and if_changed_rule. The easy fix was to insert a dummy command first in rule_ksym_ld. The alternative was to redo part of this processing in the top-level Makefile - a volatile area that I try to avoid.

* kbuild: introduce Kbuild.includeSam Ravnborg2005-07-25
| | | | | | | | | | Kbuild.include is a placeholder for definitions originally present in both the top-level Makefile and scripts/Makefile.build. There were a slight difference in the filechk definition, so the most videly used version was kept and usr/Makefile was adopted for this syntax. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> ---
* kbuild: drop descend - converting existing usersSam Ravnborg2005-07-25

* kbuild: drop -Wundef from HOSTCFLAGS for nowSam Ravnborg2005-07-25
| | | | | | | | | | -Wundef caused warnings in the bison generated code in kconfig. Updating to a newer bison (1.875d) did not fix it. The alternatives was to correct the autogenerated code or drop -Wundef. For now -Wundef is dropped from HOSTCFLAGS. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> ---
* [PATCH] kbuild: add -Wundef to global CFLAGSOlaf Hering2005-07-21
| | | | | | | | | | A recent change to the aic scsi driver removed two defines to detect endianness. cpp handles undefined strings as 0. As a result, the test turned into #if 0 == 0 and the wrong code was selected. Adding -Wundef to global CFLAGS will catch such errors.

* [PATCH] kbuild: When checking depmod version, redirect stderrTom Rini2005-07-17
| | | | | | | | | | When running depmod to check for the correct version number, extra output we don't need to see, such as "depmod: QM_MODULES: Function not implemented" may show up. Redirect stderr to /dev/null as the version information that we do care about comes to stdout. Signed-off-by: Tom Rini <trini@kernel.crashing.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

* kbuild: Don't fail if include/asm symlink existsSam Ravnborg2005-07-14
| | | | | | | | | | | | | | | | | | | | | | | From: Andreas Gruenbacher <agruen@suse.de> We're having the following situation: There are user-space applications that include kernel headers directly. With a completely unconfigured /usr/src/linux tree, including most headers fails because essential files are not there: include/asm include/linux/autoconf.h include/linux/version.h So we create these files. On the other hand, we want to use /usr/src/linux as read-only source for building kernels or additional modules. Now when building a kernel with a separate output directory (O=), there is a check in the main makefile for the include/asm symlink. There is no real need for this check: if we ensure that $(objdir)/include/asm is always created as the patch does, $(srctree)/include/asm becomes irrelevant.

* [PATCH] kbuild: allow cscope to index multiple architecturesIan Campbell2005-07-13
| | | | | | | | | | | | | | | | | I have a single source tree which I cross compile for a couple of different architectures using ARHC=foo O=blah etc. The existing cscope target is very handy but only indexes the current $(ARCH), which is a pain since inevitably I'm interested in the other one at any given time ;-). This patch allows me to pass a list of architectures for cscope to index. e.g. make ALLSOURCE_ARCHS="i386 arm" cscope This change also works for etags etc, and I presume it is just as useful there.

* [PATCH] kbuild: make 'cscope -q' play well with cscope.elKarl Hegbloom2005-07-13
| | | | | | | | | | | | | | | | | | | I tried the Linux Makefile 'make cscope' target, and found that the generated database is not compatible with 'cscope.el' under XEmacs. The thing is that 'cscope.el' does not allow setting the command line options to the 'cscope' commands it runs, and it errors with a message about the options not matching the ones used to generate the index. It turns out the cscope designers already thought of this. The options can be written into the "cscope.files". The included patch moves the "-q" and "-k" options from the 'cmd_cscope' to the 'cmd_cscope-file', echoing them into the top of the files listing. Now the index is generated with the "-q" option, and when 'cscope.el' performs it's search, it uses that argument as well. Lookups are fast and everyone is happy.

* [PATCH] kbuild: build a single module using 'make dir/module.ko'Sam Ravnborg2005-07-07
| | | | | | | | | | | | | | Using the syntax: make dir/module.ko kbuild now allows one to build a module including the final link stage. This is usefull when one only wants to compile a single module and thus do not have to wait until a full kernel has finished compiling.

* [PATCH] Turn off sibling call optimization w/ frame pointersMatthias Urlichs2005-06-23
| | | | | | | | | | | | Frame pointers are supposed to enable debuggers to reliably tell where a call comes from. That is defeated by GCC's sibling call optimization (aka tail recursion elimination). This patch turns this optimization off when compiling with frame pointers.

* [PATCH] Makefile include path orderingRik van Riel2005-05-17
| | | | | | | | | | | | | | The arch Makefile may override the include path order, which is used by Xen (and UML?) to make sure include/asm-xen is searched before include/asm-i386. The Makefile change to 2.6.12-rc4 made the top Makefile always override the value specified by the arch Makefile. This trivial patch makes the Xen kernel compile again.

* [PATCH] Makefile: fix for compatibility with *emacs ctagsEmanuele Giaquinta2005-05-01
| | | | | | | | | | | I've noticed that, starting from linux-2.6.12-rc1, in the top Makefile the "cmd_tags" variable has been changed in a way incompatible with *emacs ctags. Since the "--extra" option exists only in "exuberant ctags", it should be included in the CTAGSF shell variable.

* [PATCH] kbuild: Set NOSTDINC_FLAGS late to speed up compile (a little)Sam Ravnborg2005-04-30
| | | | | | | | | | | | | | | Move definition of NOSTDINC_FLAGS below inclusion of arch Makefile, so any arch specific settings to $(CC) takes effect before looking up the compiler include directory. The previous solution that replaced ':=' with '=' caused gcc to be invoked one additional time for each directory visited. This decreases kernel compile time with 0.1 second (3.6 -> 3.5 seconds) when running make on a fully built kernel Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
