kbuild: fix section mismatch check for vmlinux

2007-05-02T18:58:07+00:00

vmlinux does not contain relocation entries which is
used by the section mismatch checks.
Reported by: Atsushi Nemoto 

Use the individual objects as inputs to overcome
this limitation.
In modpost check the .o files and skip non-ELF files.

[PATCH] kbuild: allow multi-word $M in Makefile.modpost

2006-10-17T15:18:48+00:00

Some people want to do crazy things like pass multiple directories as the
value of $(SUBDIRS) or $M.  Mostly this kinda works, except that
Makefile.modpost constructs a modpost commandline which fails modpost's
argument parsing.  This patch fixes that little wrinkle.

kbuild: make modpost processing configurable

2006-10-01T09:35:24+00:00

On request from Al Viro make modpost processing configurable.

KBUILD_MODPOST_WARN can be set to make modpost warn instead of
error out in case on unresolved symbols in final module link.

KBUILD_MODPOST_NOFINAL can be set to avoid the final and timeconsuming
.c file generation and link of .ko files. This is solely useful for
speeding up when doing compile checks with for example allmodconfig

kbuild: fail kernel compilation in case of unresolved module symbols

2006-09-25T07:14:30+00:00

At stage 2 modpost utility is used to check modules.  In case of unresolved
symbols modpost only prints warning.

IMHO it is a good idea to fail compilation process in case of unresolved
symbols (at least in modules coming with kernel), since usually such errors
are left unnoticed, but kernel modules are broken.

- new option '-w' is added to modpost:
  if option is specified, modpost only warns about unresolved symbols

- modpost is called with '-w' for external modules in Makefile.modpost

kbuild: modpost on vmlinux regardless of CONFIG_MODULES

2006-09-25T07:01:49+00:00

Based on patch from: Magnus Damm 
This has the advantage that all section mismatch checks are run regardless
of modules being enabled or not.

When running modpost on vmlinux output:
MODPOST vmlinux

When running modpost on modules output count of modules like this:
MODPOST 5 modules

kbuild: fix ia64 breakage after introducing make -rR

2006-07-01T07:58:02+00:00

kbuild used $¤(*F to get filename of target without extension.
This was used in several places all over kbuild, but introducing
make -rR broke his for all cases where we specified full path to
target/prerequsite. It is assumed that make -rR disables old style
suffix-rules which is why is suddenly failed.

ia64 was impacted by this change because several div* routines in
arch/ia64/lib are build using explicit paths and then kbuild failed.

Thanks to David Mosberger-Tang  for an explanation
what was the root-cause and for testing on ia64.

This patch also fixes two uses of $(*F) in arch/um

Revert "kbuild: fix make -rR breakage"

2006-06-26T23:59:26+00:00

This reverts commit e5c44fd88c146755da6941d047de4d97651404a9.

Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.

Daniel says:

  "[The] reason is a recent change that made modules always shows as
   module.mod.  it breaks modprobe and probably many scripts..besides
   lsmod looking horrible

   stuff like this in modprobe.conf:
        install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
   makes modprobe fork/exec endlessly calling itself...until oom
   interrupts it"

kbuild: fix make -rR breakage

2006-06-24T21:13:59+00:00

make failed to supply the filename when using make -rR and using $(*F)
to get target filename without extension.
This bug was not reproduceable in small scale but using:
$(basename $(notdir $@)) fixes it with same functionality.

kconfig: fix .config dependencies

2006-06-09T05:31:30+00:00

This fixes one of the worst kbuild warts left - the broken dependencies used
to check and regenerate the .config file.  This was done via an indirect
dependency and the .config itself had an empty command, which can cause make
not to reread the changed .config file.

Instead of this we generate now a new file include/config/auto.conf from
.config, which is used for kbuild and has the proper dependencies.  It's also
the main make target now for all files generated during this step (and thus
replaces include/linux/autoconf.h).

This also means we can now relax the syntax requirements for the .config file
and we don't have to rewrite it all the time, i.e.  silentoldconfig only
writes .config now when it's necessary to keep it in sync with the Kconfig
files and even this can be suppressed by setting the environment variable
KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.
