2009-06-09scripts/headers_check.pl: correct RE in header CONFIG leak checkRobert P. J. Day
Correct the regular expression in scripts/headers_check.pl to include '_' as a valid character in the class; otherwise, the check will report a "leaked" symbol of CONFIG_A_B_C as merely CONFIG_A. This patch will make no difference whatsoever in the current kernel tree as the call to the perl routine that does that check is currently commented out: &check_include(); &check_asm_types(); &check_sizetypes(); &check_prototypes(); # Dropped for now. Too much noise &check_config(); However, I noticed that problem when I was building the yum downloadable kernel source rpm for fedora 11 (beta), which *does* run that check, and that's where the problem became obvious.

2009-06-09kconfig: do not hardcode "include/config/auto.conf" filenameMarkus Heidelberg
Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target into "include/config/auto.conf.cmd" was always the default one.

2009-05-02Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson
The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

2009-05-01kbuild, modpost: Check the section flags, to catch missing "ax"/"aw"Anders Kaseorg
When you put .section ".foo" in an assembly file instead of .section "foo", "ax" , one of the possible symptoms is that modpost will see an ld-generated section name ".foo.1" in section_rel() or section_rela(). But this heuristic has two problems: it will miss a bad section that has no relocations, and it will incorrectly flag many gcc-generated sections as bad when compiling with -ffunction-sections -fdata-sections. On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one: WARNING: crypto/cryptd.o (.text.T.349): unexpected section name. So instead of checking whether the section name matches a particular pattern, we directly check for a missing SHF_ALLOC in the section flags.

2009-05-01kbuild: fix Module.markers permission error under cygwinCedric Hombourger
While building the kernel, we end-up calling modpost with -K and -M options for the same file (Modules.markers). This is resulting in modpost's main function calling read_markers() and then write_markers() on the same file. We then have read_markers() mmap'ing the file, and writer_markers() opening that same file for writing. The issue is that read_markers() exits without munmap'ing the file and is as a matter holding a reference on Modules.markers. When write_markers() is opening that very same file for writing, we still have a reference on it and cygwin (Windows?) is then making fopen() fail with EPERM. Calling release_file() before exiting read_markers() clears that reference (and memory leak) and fopen() then succeeds. Tested on both cygwin (1.3.22) and Linux. Also ran modpost within valgrind on Linux to make sure that the munmap'ed file was not accessed after read_markers() Signed-off-by: Cedric Hombourger <chombourger@gmail.com> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2009-05-01kbuild: remove a tag file before it is regeneratedMatt Kraai
If a tag file is not removed before it is regenerated, the newly generated data is appended to the old, which preserves stale data and makes the tag file grow over time. Signed-off-by: Matt Kraai <kraai@ftbfs.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2009-04-27Remove unused support code for refok sections.Tim Abbott
The old refok sections .text.init.refok .data.init.refok .exit.text.refok have been deprecated since commit 312b1485fb509c9bc32eda28ad29537896658cb8. After the other patches in this patch series nothing is put in these sections, so clean things up by eliminating all the remaining references to them.

2009-04-19kbuild: introduce subdir-ccflags-ySam Ravnborg
Following patch introduce support for setting options to gcc that has effect for current directory and all subdirectories. The typical use case are an architecture or a subsystem that decide to cover all files with -Werror. Today alpha, mips and sparc uses -Werror in almost all their Makefile- with subdir-ccflag-y it is now simpler to do so as only the top-level directories needs to be covered. Likewise if we decide to cover a full subsystem such as net/ with -Werror this is done by adding a single line to net/Makefile.
