kbuild: use LDFLAGS_MODULE only for .ko links

2007-07-25T19:18:19+00:00

Sam Ravnborg pointed out that Documentation/kbuild/makefiles.txt already
says this is what it's for.  This patch makes the reality live up to the
documentation.  This fixes the problem of LDFLAGS_BUILD_ID getting into too
many places.

kbuild: do not do section mismatch checks on vmlinux in 2nd pass

2007-07-25T19:14:15+00:00

We already check and warn about section mismatches from vmlinux
(build as vmlinux.o) during first pass so skip the checks
during the 2nd pass where we process modules.

kbuild: do section mismatch check on full vmlinux

2007-07-17T08:54:06+00:00

Previously we did do the check on the .o files used to link
vmlinux but that failed to find questionable references across
the .o files.
Create a dedicated vmlinux.o file used only for section mismatch checks
that uses the defualt linker script so section does not get renamed.

The vmlinux.o may later be used as part of the the final link of vmlinux
but for now it is used fo section mismatch only.
For a defconfig build this is instant but for an allyesconfig this
add two minutes to a full build (that anyways takes ~2 hours).

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
