2008-01-28kbuild: scripts/mkmakefile: dynamic determination of output directoryJan Beulich
Rather than fixing the output directory in the generated Makefile, determine it from the placement of Makefile. This allows moving the build tree around or accessing it through different mount paths. (The lastword definition is a compatibility one for make prior to 3.81; newer make will simply ignore it and use the [faster] built-in.)

2008-01-28kbuild: clean up modpost.cSam Ravnborg
akpm complained about overly long lines in modpost.c and when started additional style issues were fixed: o Updated my copyright o Removed unneeded {} o Drop assignments in if () o Spaces around operators o Break long lines o locate * near variable not type o Fix a format specifier for sizeof() o Corrected placement of '{' and '}' o spaces to tabs (but use tabs only for indention) modpost.c is not checkpatch clean. Readability were favoured on top of checkpatch compliance. But checkpatch were used to find additional stuff to clean up. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2008-01-28kconfig: make kconfig MinGW friendlyLadislav Michl
Kconfig is powerfull tool. So powerfull that more and more software projects are using it for configuration. So instead of fixing some of them one by one, lets fix it in kernel and wait for sync. This work was originaly done for PTXdist - GPL licensed build system for userlands and cross-compilers, but it will not hurt kernel kconfig either. PTXdist menuconfig now works on Windows linked with PDCurses and compiled using MinGW - there is no termios and signals. * Do not include <sys/wait.h> and <signal.h> (comes from times when lxdialog was separate process) * Do not mess with termios directly and let curses tell screen size. Comment to commit c8dc68ad0fbd934e78e913b8a8d7b45945db4930 says check for screen size could be removed later, but because it didn't happen for more than year I left it here as well. * Save cursor position added by Sam Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

2008-01-28kbuild: fix false positive -dirty tag caused by make-kpkgTheodore Ts'o
make-kpkg modifies scripts/package/Makefile and deletes scripts/package/builddeb as part of its build process. Ignore these changes so the tree isn't marked as -dirty, when it is just an artifact of make-kpkg. (make-kpkg clean restores the files to their original state, and these helper scripts won't affect the final compiled kernel in any way.)

2008-01-28kbuild: fix scripts/setlocalversion to avoid erroneous -dirty tagTheodore Ts'o
If git's index file is out of date, and some files have been touched such that their timestamp doesn't what is in the index, "git diff-index HEAD" may show that a particular file is dirty, when in fact it really isn't. Running "git update-index" will update the index to avoid these false positives. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-01-28kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish formatTheodore Ts'o
Change the automatic local version to have the form -nnnnn-gSHA1SUMID, where 'nnnnn' is the number of commits since the last tag (i.e., 2.6.21-rc7). This makes it much more likely that the package names created for the kernel will look "newer" to a package manager.

2008-01-28kbuild: eradicate bashisms in scripts/patch-kernelAndreas Mohr
Make the patch-kernel shell script sufficiently compatible with POSIX shells, i.e., remove bashisms from scripts/patch-kernel. This means that it now also works on dash 0.5.3-5 and still works on bash 3.1dfsg-8. Full changelog: - replaced non-standard "==" by standard "=" - replaced non-standard "source" statement by POSIX "dot" command - use leading ./ on mktemp filename to force the tempfile to a local directory, so that the search path is not used - replace bash syntax to remove leading dot by similar POSIX syntax - added missing (optional/not required) $ signs to shell variable names Signed-off-by: Andreas Mohr <andi@lisas.de> Acked-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2008-01-28kbuild: fixup genksyms usage/getoptMike Frysinger
The usage does not mention the "-a,--arch" or "-T,--dump-types" options, so add them. The calls to getopt() seem to mention options that no longer exist (some "k" and "p" thingy) but omits the "h" option which means using '-h' actually triggers the error code path, so update those as well.

2008-01-28kconfig: use getopt() in conf.c for handling command line argumentsAndres Salomon
Switch from doing our own parsing of command line arguments to using getopt(3) to do it. Aside from simplifying things, this allows us to specify multiple arguments; the old code could only accept two arguments (input_mode and kconfig name). Note some subtle changes: - The argument '-?' is no longer supported. - '-h' is not treated as an error, so output goes to stdout, and we exit with '0'. - There is no compatibility checking amongst arguments; the last option will simply override earlier options. For example, 'conf -n -y foo' is perfectly valid now (input_mode will be set_yes). Previously, that would have been an error ("can't find file -y").

2008-01-28kbuild: implement modules.orderTejun Heo
When multiple built-in modules (especially drivers) provide the same capability, they're prioritized by link order specified by the order listed in Makefile. This implicit ordering is lost for loadable modules. When driver modules are loaded by udev, what comes first in modules.alias file is selected. However, the order in this file is indeterministic (depends on filesystem listing order of installed modules). This causes confusion. The solution is two-parted. This patch updates kbuild such that it generates and installs modules.order which contains the name of modules ordered according to Makefile. The second part is update to depmod such that it generates output files according to this file. Note that both obj-y and obj-m subdirs can contain modules and ordering information between those two are lost from beginning. Currently obj-y subdirs are put before obj-m subdirs. Sam Ravnborg cleaned up Makefile modifications and suggested using awk to remove duplicate lines from modules.order instead of using separate C program.
