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 <David.Mosberger@acm.org> for an explanation
what was the root-cause and for testing on ia64.

When the verbose (-v) option is used with scripts/kernel-doc, this option
reports when the kernel-doc format is malformed and apparently contains
function description lines before function parameters. In these cases, the
kernel-doc script will print something like: Warning(filemap.c:335):
contents before sections
I have fixed the problems in mm/filemap.c and added lots of kernel-doc to
that file (posted to the linux-mm mailing list Mon. 2006-June-12).
The real goal (as requested by Andrew Morton) is to allow the short
function description to be more than one line long. This patch is both a
kernel-doc checker and a tool en route to that goal.

Finding "init_module" high stack usage problems is challenging when there
are over 1600 "init_module" functions in the kernel tree, so make
checkstack.pl print out the filename where the stack usage occurs. This is
useful for code built as loadable modules.
For built-in code, it just prints the kernel image file name, like
"vmlinux". Examples:
(before patch:)
0x0000000d callback: 1928
0xffffffff81678c09 huft_build: 1560
0x0018 init_module: 1512

Drop leading space of kernel-doc section contents.
"Section" data (contents) are split from the section header
(e.g., Note: below is a section header:

* in an undefined state.

Currently the data/contents begins with a space and is left that way, which
causes it to look bad when printed (in text mode; see example below), so
just remove the leading space.

Here is a patch that adds a new -T option to genksyms for generating dumps of
the type definition that makes up the symbol version hashes. This allows to
trace modversion changes back to what caused them. The dump format is the
name of the type defined, followed by its definition (which is almost C):
s#list_head struct list_head { s#list_head * next , * prev ; }
The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef.
The exported symbols do not define types, and thus do not have an x# prefix:
nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 )
The symbol type defintion of a single file can be generated with:
make fs/jbd/journal.symtypes
If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that
export symbols are generated.
The single *.symtypes files can be combined into a single file after a kernel
build with a script like the following:
for f in $(find -name '*.symtypes' | sort); do
f=${f#./}
echo "/* ${f%.symtypes}.o */"
cat $f
echo
done \
| sed -e '\:UNKNOWN:d' \
-e 's:[,;] }:}:g' \
-e 's:\([[({]\) :\1:g' \
-e 's: \([])},;]\):\1:g' \
-e 's: $::' \
$f \
| awk '
/^.#/ { if (defined[$1] == $0) {
print $1
next
}
defined[$1] = $0
}
{ print }
'
When the kernel ABI changes, diffing individual *.symtype files, or the
combined files, against each other will show which symbol changes caused the
ABI changes. This can save a tremendous amount of time.

Add option for stripping modules while installing them.
This function adds support for stripping modules while they are being
installed. CONFIG_DEBUG_KERNEL (which will probably become more
popular as developers use kdump) causes the size of the installed
modules to grow by a factor of 9 or so.
Some kernel package systems solve this problem by stripping the debug
information from /lib/modules after running "make modules_install",
but that may not work for people who are installing directly into
/lib/modules --- root partitions that were sized to handle 16 megs
worth of modules may not be quite so happy with 145 megs of modules,
so the "make modules_install" never succeeds.
This patch allows such users to request modules_install to strip the
modules as they are installed.

Now that kconfig can load multiple configurations, it becomes simple to
integrate the split config step, by simply comparing the new .config file with
the old auto.conf (and then saving the new auto.conf). A nice side effect is
that this saves a bit of disk space and cache, as no data needs to be read
from or saved into the splitted config files anymore (e.g. include/config is

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.
