* kbuild: do not include arch/<ARCH>/include/asm in find-sources twice.Ian Campbell2008-10-291-1/+2
| | | | | | | | | | | | Architectures which have moved their includes to arch/<ARCH>/include now list the headers twice in the source listing used by "make cscope" and friends, causing those tools to list symbols twice. Skipping these files in the ALLSOURCE_ARCHS pass rather than removing the ALLINCLUDE_ARCHS pass preserves the semantics of the later.

* kbuild: improve check-symlinkSam Ravnborg2008-10-291-0/+5
| | | | | | | | | | | | | o if include/asm point to a nonexisting directory remove the asm symlink o if include/asm is a directory error out This fixes a situation where one could be left with a symlink to asm-x86 but that directory no longer exist and thus the build would error out. include/asm may be a directory if the kernel tree has been copied Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

* | ftrace: rename FTRACE to FUNCTION_TRACERSteven Rostedt2008-10-201-1/+1
|/ | | | | | | | | | | | Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER. The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.

* docsrc: build Documentation/ sourcesRandy Dunlap2008-08-121-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | Currently source files in the Documentation/ sub-dir can easily bit-rot since they are not generally buildable, either because they are hidden in text files or because there are no Makefile rules for them. This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds). Built (using cross-tools) for x86-64, i386, alpha, ia64, sparc32, sparc64, powerpc, sh, m68k, & mips.

* kbuild: a better way to generate cscope database changeDenis ChengRq2008-08-061-1/+1
| | | | | | | | | | | | | | | | | | It's a problem about cscope target of kernel Makefile, and the cscope plugin of emacs: 1. `make cscope` will generate cscope.files cscope.{in,po,}.out; 2. the cscope plugin expect a cscope.out.{in,po,}; 3. the default `cscope -b` would generate cscope.{in,po,}.out; There are three approach to solve it: 1. modify the cscope C code; 2. modify the cscope emacs plugin lisp code; 3. modify the Makefile; I have tried to communicate with the cscope upstream, but later I realize the third approach is most meaningful.

* kbuild: fix O=.. build with armSam Ravnborg2008-08-061-3/+3
| | | | | | | | | | | | | | | | | With a make O=... build kbuild would only create the include2/asm symlink for archs that not yet had moved headers to include/$ARCH/include There is no longer any reason to avoid the symlink for archs that has moved their headers so create it unconditionally. This fixes arm because kbuild checked for include/asm-$ARCH/errno.h and that file was not present for arm but the platform files are not yet moved.

This revealed a long standing bug where "make headers_check_all" relied on the files in asm/ for the current architecture. So make headers_check_all is now broken by this commit. In addition: o add a simpler way to detect if an arch support exporting header files. o add 'set -e;' so we error out early if make headers_check_all fails. o add sparc64 and cris to arch we do not process in make headers_*_all because: sparc64 - use sparc to export headers cris - is know seriously broken Includes suggestions from: David Woodhouse <dwmw2@infradead.org>.

| | | | | | | | | | | | | | | | | | | | | | Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler and gcc 3.4.6 for the mips-linux target results in the following build error: $ make malta_defconfig $ make cc1: error: unrecognized command line option "-fno-stack-protector" scripts/kconfig/conf -s arch/mips/Kconfig cc1: error: unrecognized command line option "-fno-stack-protector" The arch Makefile is included too late so the host compiler is feature tested, not the crosscompiler as intended and thus the Makefile applies adds -fno-stack-protector to crosscompiler's flags which fails for gcc 3.4.6. The bug was introduced by e06b8b98da071f7dd78fb7822991694288047df0 in 2.6.25; 35bb5b1e0e84cfa1a8906f7e6a77f391ff315791 did add more flags testing before the arch Makefile inclusion.
