#   [PATCH] kbuild: skip depmod if not executable
#   
#   I've cross-compiled Linux on i386-netbsdelf2.0 for
#   arm-linux for quite some time now and everything seems
#   to be working perfectly except for one minor glitch in
#   the build process that halts module installation
#   (needlessly, IMHO). Specifically, if System.map exists
#   $(DEPMOD) is run ("for convenience" as the comment
#   says in the Makefile). However, on NetBSD I don't have
#   $(DEPMOD) available so the command fails and make
#   exits with non-zero exit status. Please consider the
#   attached patch to add a check for $(DEPMOD) so that
#   missing $(DEPMOD) won't halt the whole build process.

#   [PATCH] kbuild: fix for i386 cross compile
#   
#   I used to be be able to cross compile for i386 on my x86_64 machine,
#   but recently something (gcc/binutils?) changed, and it stopped working.
#   
#   Following patch makes cross compile work with:
#   
#   make ARCH=i386 CFLAGS_KERNEL="-m32" AFLAGS_KERNEL="-m32" bzImage
#   
#   Without the patch I'm getting the following error:
#

#   [PATCH] kbuild: no redundant srctree in tags file
#   
#   Avoid cluttering the tags/TAGS generated file with $(srctree) in the paths
#   if this is not needed.
#   
#   This has two advantages:
#   
#   - Saving about 20M on the size of the resulting tags file (which are used
#     currently to store the absolute path of the file names rather than the
#     relative one) when KBUILD_OUTPUT is not set.
#   
#   - Keeping the tags file valid when the directory is renamed.
#   
#   No change is done for who does make tags O=..., if this is wanted (I would
#   find that incommodous and non-typical for a developer, but anyway I've not
#   ruined functionality in that case).

#   [PATCH] kbuild: Use -Wno-pointer-sign for gcc 4.0
#   
#   Compiling an allyesconfig kernel straight with a gcc 4.0 snapshot
#   gives nearly 10k new warnings like:
#   
#   warning: pointer targets in passing argument 5 of `cpuid' differ in signedness
#   
#   Since the sheer number of these warnings was too much even for the
#   most determined kernel janitors (I actually asked ;-) and I don't
#   think it's a very serious issue to have these mismatches I submitted
#   an new option to gcc to disable it. It was incorporated in gcc mainline
#   now.
#   
#   This patch makes the kernel compilation use it. There are still
#   quite a lot of new warnings with 4.0 (mostly about uninitialized variables),
#   but the compile log looks much nicer nnow.

#   In more complicated cases, we get syntax erros.  Re-introduce the

#   kbuild: Warn when building external modules without modversions
#   
#   This adds a warning when building external modules (M= or SUBDIRS=
#   syntax) and there is no Module.symvers in the object tree. A missing
#   Module.symvers is a clear sign that the kernel tree itself was never
#   compiled. The resulting modules will work, but no symbol version
#   information will be attached to kernel symbols the module uses (because
#   that information comes from Module.symvers), and so the module will be
#   more unsafe.
#   Futhermore the external module will not record what other modules it is
#   depended on.
#   
#   The test works with CONFIG_MODVERSIONS enabled or disabled.
