* kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg2007-10-14
| | | | | | | | | | | | | | | | | | | | | | | The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

* kbuild: fix up CFLAGS usageSam Ravnborg2007-10-14

* kconfig/menuconfig: distinguish between selected-by-another options and commentsMatej Laitl2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | menuconfig currently represents options implied by another option ('select' directive in Kconfig) by prefixing them with '---'. Unfortunately the same notation is used for comments. If the implied option is module capable, user can still switch between Y and M, all without any feedback until she visits option's help. (try saying M to MAC80211 and then toggling CFG80211) This patch changes notation of selected-by-another items by introducing 2 new representations for implied options: {*} or {M} for options selected by another modularized one, thus builtin or module capable, -*- or -M- for options that cannot be at the moment changed by user. The idea is to represent actual capability of the option by braces (dashes) around and to always report actual state by * or M inside.

* kbuild: call make once for all targets when O=.. is usedMilton Miller2007-10-12
| | | | | | | | | | | | | | | | | | | | | | Change the invocations of make in the output directory Makefile and the main Makefile for separate object trees to pass all goals to one $(MAKE) via a new phony target "sub-make" and the existing target _all. When compiling with separate object directories, a separate make is called in the context of another directory (from the output directory the main Makefile is called, the Makefile is then restarted with current directory set to the object tree). Before this patch, when multiple make command goals are specified, each target results in a separate make invocation. With make -j, these invocations may run in parallel, resulting in multiple commands running in the same directory clobbering each others results. I did not try to address make -j for mixed dot-config and no-dot-config targets. Because the order does matter, a solution was not obvious. Perhaps a simple check for MAKEFLAGS having -j and refusing to run would be appropriate. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: pass -g to assembler under CONFIG_DEBUG_INFORoland McGrath2007-10-12
| | | | | | | | | | | | | | The assembler for a while now supports -gdwarf to generate source line info just like the C compiler does. Source-level assembly debugging sounds like an oxymoron, but it is handy to be able to see the right source file and read its comments rather than just the disassembly. This patch enables -gdwarf for assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.

* kbuild: scripts/ver_linux : correct printing of binutils versionJesper Juhl2007-10-12
| | | | | | | | | | | | | | | | Currently scripts/ver_linux prints "Binutils" or other random information for the version number in the "binutils" output line on some distributions. This patch corrects that. When I initially submitted a patch to correct that, I was not aware that the output from "ld -v" could differ as much as it turned out it can, so my original fix turned out to not cover all bases. This patch works correctly with all the different "ld -v" output that people posted in replys to my first patch, so it should be a clear win over what we have currently.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid having to look manually for used but undefined Kconfig variables, I've written a script which tries do this efficiently, in case all other attention fail. It accounts for _MODULE suffix and for UML_ prefixes to Kconfig variable, but otherwise looks for exact matches (i.e. \<CONFIG_; this is done to exclude macros like MMCONFIG_). Undefined Kconfig variables should be not be removed without care, but for instance arch/i386/boot/ uses a bunch of undefined Kconfig vars: $ scripts/checkunknowndefines.sh arch/i386/boot/ arch/i386/boot/video.h uses undefined symbol VIDEO_400_HACK arch/i386/boot/video-vga.c uses undefined symbol VIDEO_400_HACK arch/i386/boot/video.c uses undefined symbol VIDEO_RETAIN arch/i386/boot/video.h uses undefined symbol VIDEO_RETAIN arch/i386/boot/video.h uses undefined symbol VIDEO_SVGA arch/i386/boot/video.h uses undefined symbol VIDEO_VESA arch/i386/boot/video-vesa.c uses undefined symbol VIDEO_VESA It should also be mentioned in SubmittingPatches and SubmitChecklist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.

| * [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here.
