This version of unistd.h has gone through intensive review to make sure that by default it only enables syscalls that do not already have a more featureful replacement. It is modeled after the x86-64 version of unistd.h, which unifies the syscall number definition and the actual system call table in a single file, in order to keep them synchronized much more easily. This first version still keeps legacy system call definitions around, guarded by various #ifdefs, and with numbers larger than 1024. The idea behind this is to make it easier for new architectures to transition from a full list to the reduced set. In particular, the new microblaze architecture that should migrate to using the generic ABI headers can at least use an existing uClibc source tree without major rewrites during the conversion.

* | Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson2009-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | kbuild, modpost: Check the section flags, to catch missing "ax"/"aw"Anders Kaseorg2009-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using trees like wireless-testing, which have untagged tags, scripts/setlocalversion does not display any git indication for localversion. This patch fixes it: If git is available, but no usable tag is found, it uses -g${head}. It skips the detection of unanottated tags via git name-rev.

| * | kbuild: fix Module.markers permission error under cygwinCedric Hombourger2009-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scripts/kernel-doc can (incorrectly) delete struct members that are surrounded by /* ... */ <struct members> /* ... */ if there is a /* private: */ comment in there somewhere also. Fix that by making the "/* private:" only allow whitespace between /* and "private:", not anything/everything in the world. This fixes some erroneous kernel-doc warnings that popped up while processing include/linux/usb/composite.h.

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.

* | kbuild: introduce subdir-ccflags-ySam Ravnborg2009-04-19
|/ | | | | | | | | | | | | | | | | | | | | 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.

| * kbuild: fix spurious initramfs rebuildMaxime Bizon2009-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When gen_initramfs_list is used to generate make dependencies, it includes symbolic links, for which make tracks the link target. Any change to that target will cause an initramfs rebuild, even if the symlink points to something outside of the initramfs directory. If the target happens to be /tmp, the rebuild occurs for each kernel build, since gen_initramfs_list uses mktemp... Proposed way to fix it is to omit symbolic links from generated dependencies, but this has a small drawback: changing perm/owner on a symlink will go unnoticed.
