The ver_linux script is fixed to report recent versions of
reiserfsprogs. (Older versions had "reiserfsprogs" in the
line containing the version number, while recent versions
report "reiserfsck" followed by version number).
The ver_linux script is updated to report the reiser4progs
version number.
This was tested with reiserfsprogs 3.6.11, 3.6.18 and
reiser4progs 1.0.0.

make namespacecheck lists globally visible symbols that are not used
outside the file that defines them. These symbols are candidates for
static declarations. It also lists multiply defined symbols.
namespace.pl knows about lots of special cases in the kernel code,
including exported symbols and conglomerate objects.
The patch also corrects the usage of scripts/reference*.pl, they need
$(src).

Additional Makefile fixes for Solaris 2.8
On Solaris, 'head' doesn't take a -q argument. But we can use 'grep -h'
instead, so do that in Makefile.mod{inst,post}. The built-in test to
/bin/sh doesn't like 'if ! cmd' syntax, so when determining if we need
to do modversion stuff, invert the if/else cases. The built-in test
also doesn't understand -ef, so invoke a real version of test which does.

However, on Cygwin (the other odd place that the kernel is compiled

When compiling Linux on Mac OSX I had trouble with scripts/sumversion.c.
It includes <netinet/in.h> to obtain to definitions of htonl and ntohl.
On Mac OSX these are found in <arpa/inet.h>. After checking the POSIX
specification it appears that this is the correct place to get the
definitons for these functions.
(http://www.opengroup.org/onlinepubs/009695399/functions/htonl.html)
Using this header also appears to work on Linux (at least with
Glibc-2.3.2).
It seems clearer to me to go with the POSIX standard than implementing
#if __APPLE__ style macros, but if such an approach is preferred I can
supply patches for that instead.
A patch against 2.6.7 which change <netinet/in.h> -> <arpa/inet.h> is
attached.

You probably saw that if you change one config option, even if
linux/autoconf.h (which is included by everything) changes, the kernel is
smart enough not to recompile everything. But with UML this no more holds.
Why? Because, as you see in this patch, fixdep avoids making anything depend
onto linux/autoconf.h *explicitly*, but nobody taught him to do the same for
arch/um/include/uml-config.h. So apply this patch. Do not say "I don't want
to change the generic Kbuild for one arch": this cannot hurt. It's a bugfix
for us, a no-op for others.
Note: with this patch, fixdep will still add a dependency from a file
containing UML_CONFIG_BYE onto CONFIG_BYE. Since someone could think that
fixdep should grep for [^A-Z_]CONFIG_ rather than simply for CONFIG_, I've
added a comment that ask *not to fix* this "bug".

Update 'scripts/patch-kernel' to support EXTRAVERSION.
Update usage message text.
Fix some whitespace.
Handle command line arg3 (stop-version) more carefully.
No changes to -ac patch updates.
EXTRAVERSION handling:
any leading '.' and any trailing modifier (beginning with any
punctuation, like "-ac" or "_kexec" or "+mm") are stripped,
trying to get down to just a number.
Then 'patch-kernel' increments EXTRAVERSION as long as it can
apply "patch-V.P.S.X*". When that file isn't found, it resets
EXTRAVERSION to "" and increments SUBLEVEL (as before this patch).
Works for me.

Russell King reported that some gcc / bin-utils combination may result in
undefined symbols in vmlinux and implemented a check for that.
Though the cause is very valid this check has proved to be a real pain
for other users, especially sparc and um.
Short term a similar check is asked to be implemented in arch/arm*/Makefile
and long-term to bail out if too old gcc / bin-utils is used.
Long term plan awaits a new gcc / bin-utils release.

Only warn if $(host-progs) and $(hostptogs-y) are not equal.

From: Pavel Roskin <proski@gnu.org>
The recent fixes for the external module build have fixed the major
breakage, but they left one annoyance unfixed. If CONFIG_MODVERSIONS is
disabled, a warning is printed for every exported symbol that is has no
CRC. For instance, I see this when compiling the standalone Orinoco
driver on Linux 2.6.6-rc3:
*** Warning: "__orinoco_down" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
*** Warning: "hermes_struct_init" [/usr/local/src/orinoco/spectrum_cs.ko]
has no CRC!
*** Warning: "free_orinocodev" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
[further warnings skipped]
I have found that the "-i" option for modpost is used for external builds,
whereas the internal modules use "-o". The "-i" option causes read_dump()
in modpost.c to be called. This function sets "modversions" variable
under some conditions that I don't understand. The comment before the
modversions declarations says: "Are we using CONFIG_MODVERSIONS?"
Apparently modpost fails to answer this question. I think it's better to
use an explicit option rather than a kludge.
The attached patch adds a new option "-m" that is specified if and only if
CONFIG_MODVERSIONS is enabled. The patch has been successfully tested
both with and without CONFIG_MODVERSIONS.

David S. Miller <davem@redhat.com> wrote:
Shouldn't we be grepping __crc_ symbols out of the System.map file?
For one thing, these can confuse readprofile. It's algorithm is
to start at _stext, then stop when it sees a line in the System.map
which is not text (mode is one of 'T' 't' 'W' or 'w')
It will exit early if there are some intermixed __crc_* things in
there (since they are are mode 'A').
For example, in my current sparc64 kernel I have this:
00000000004cef80 t do_split
00000000004cf2a0 t add_dirent_to_buf
00000000004cf5a7 A __crc_init_special_inode
00000000004cf640 t make_indexed_dir
00000000004cf900 t ext3_add_entry
So no symbols after add_dirent_to_buf will be shown in the profiling
output of readprofile.
Implementation ported to mksysmap by Sam.
Included two System.map related fixes:
- Print "SYSMAP System.map" during build
- Sort symbols in System.map

Introducing hostprogs-y allows a user to use the typical Kbuild
pattern in a Kbuild file:
hostprogs-$(CONFIG_KALLSYMS) += ...
And then during cleaning the referenced file are still deleted.
Deprecate the old host-progs assignment but kept the functionlity.
External modules will continue to use host-progs for a while - drawback is
that they now see a warning.
Workaround - just assign both variables:
hostprogs-y := foo
host-progs := $(hostprogs-y)
All in-kernel users will be converted in next patch.

At least one bin-utils version for ARM is know to ignore undefined
symbols when performing the final link of vmlinux.
Add an explicit check for undefined symbols to catch this.
The check is made in combination with generating the System.map file
and the actual algorithm is moved to a small shell script - mksysmap.
External symbols with three leading underscores are ignored - sparc
uses them for the BTFIXUP logic.

When building a kernel using the O= syntax to save output
files in a separate output directory now create a small Makefile in
that same dir.
This Makefile allow one to use make in the output directory without
the hassle of going back to the kernel source tree.
The O= option is added by this Makefile stub.
Please note that the Makefile silently overwrite an old one, so changes
will be lost if modified.
If there is a need to tweak a Makefile in the output directory it is recommended
to use the filename 'makefile', which GNU Make will try first.
