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.

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>

2008-01-28kconfig: 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.

2007-12-17fix bloat-o-meter for ppc64Nathan Lynch
bloat-o-meter assumes that a '.' anywhere in a symbol's name means that it is static and prepends 'static.' to the first part of the symbol name, discarding the portion of the name that follows the '.'. However, the names of function entry points begin with '.' in the ppc64 ABI. This causes all function text size changes to be accounted to a single 'static.' entry in the output when comparing ppc64 kernels.

2007-11-17x86: simplify "make ARCH=x86" and fix kconfig all.configSam Ravnborg
Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in all.config. For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: - 0f855aa64b3f63d35a891510cf7db932a435c116 ("kconfig: add helper to set config symbol from environment variable") - 2a113281f5cd2febbab21a93c8943f8d3eece4d3 ("kconfig: use $K64BIT to set 64BIT with all*config targets") Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.
