2007-06-11kbuild: fix sh64 section mismatch problemsSam Ravnborg
There's a special .cranges section that is almost always generated, with data being moved to the appropriate section by the linker at a later stage. To give a bit of background, sh64 has both a native SHmedia instruction set (32-bit instructions) and SHcompact (which is compatability with normal SH -- 16-bit, a massively reduced register set, etc.). code ranges are emitted when we're using the 32-bit ABI, but not the 64-bit one. It is a special staging section used solely by binutils where code with different flags get placed (more specifically differing flags for input and output sections), before being lazily merged by the linker. The closest I've been able to find to documentation is: http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/ld/emultempl/sh64elf.em?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src It's an array of 8-byte Elf32_CRange structure given in http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/bfd/elf32-sh64.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src that describes for which ISA a range is used. Silence the warnings by allowing references from .init.text to .cranges. The following warnings are fixed: WARNING: init/built-in.o(.cranges+0x0): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0xa): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x14): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x1e): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x28): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x32): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x50): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x5a): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x64): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0xfa): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x104): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x10e): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x14a): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x154): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x15e): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0x6e): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0x78): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0x82): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0xaa): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x136): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x140): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x14a): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x168): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x1f4): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x1fe): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x302): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x30c): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x316): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x3a2): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x3ac): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x4ce): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x4d8): Section mismatch: reference to .init.text: Signed-off-by: Paul Mundt <lethal@linux-sh.org> Cc: Kaz Kojima <kkojima@rr.iij4u.or.jp> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

warnings Throughout the kernel there are a few legitimite references to init or exit sections. Most of these are covered by the patterns included in modpost but a few nees special attention. To avoid hardcoding a lot of function names in modpost introduce a marker so relevant function/data can be marked.

2007-05-19powerpc: Fix the MODALIAS generation in modpost for of devicesSylvain Munaut
Since the devices may have multiple (or none) compatible properties, the uevent generated internally by the kernel may have multiple "C..." entries. So the MODALIAS stored in the module must have wilcard before and after the compatible entry. Also, if the 'compatible' field is not used for matching, there will be no 'C' and that must handled as well. The previous code handled all those case incorrectly and it "mostly" worked ... but not always.

In a different approach here's a patch that handles the special case of composite arithmetic expressions in array size initializers. With it, prior to pushing the split strings on the @first_arg array, I split the keywords before the array name as before and then keep the array name along with the subscript expression as a single whole element which gets pushed last. In this manner, kernel-doc produces correct output without removing whitespaces which makes the array subscripts unreadable in the docs.

2007-05-08Add white list into modpost.c for memory hotplug code and ia64's machvec sectionYasunori Goto
This patch is add white list into modpost.c for some functions and ia64's section to fix section mismatchs. sparse_index_alloc() and zone_wait_table_init() calls bootmem allocator at boot time, and kmalloc/vmalloc at hotplug time. If config memory hotplug is on, there are references of bootmem allocater(init text) from them (normal text). This is cause of section mismatch. Bootmem is called by many functions and it must be used only at boot time. I think __init of them should keep for section mismatch check. So, I would like to register sparse_index_alloc() and zone_wait_table_init() into white list. In addition, ia64's .machvec section is function table of some platform dependent code. It is mixture of .init.text and normal text. These reference of __init functions are valid too.

2007-05-07blackfin architectureBryan Wu
This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-06kconfig: error out if recursive dependencies are foundSam Ravnborg
Sample: config FOO bool "This is foo" depends on BAR config BAR bool "This is bar" depends on FOO This will result in following error message: error: found recursive dependency: FOO -> BAR -> FOO And will then exit with exit code equal 1 so make will stop.

2007-05-02kbuild: scripts/basic/fixdep segfault on pathological string-o-deathAndy Green
build scripts: fixdep blows segfault on string CONFIG_MODULE seen The string "CONFIG_MODULE" appearing anywhere in a source file causes fixdep to segfault. This string appeared in the wild in the current mISDN sources (I think they meant CONFIG_MODULES). But it shouldn't segfault (esp as CONFIG_MODULE appeared in a quoted string).

2007-05-02kbuild: propagate errors from find in scripts/gen_initramfs_list.shMichael Ellerman
If the find(1) in scripts/gen_initramfs_list.sh generates any errors, it will cause gen_initramfs_list.sh to fail (because of "set -e"), however the errors from find are not printed to the user. This is rather confusing: ~/src/powerpc$ make O=~/build/powerpc-cell32/ make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 make[1]: *** [usr] Error 2 make[1]: *** Waiting for unfinished jobs.... make[1]: *** wait: No child processes. Stop. make: *** [_all] Error 2 It is much easier to work out what the problem is if we let the errors from find hit the console, eg: ~/src/powerpc$ make O=~/build/powerpc-cell32/ find: /home/michael/initramfs-source/home: Permission denied find: /home/michael/initramfs-source/lost+found: Permission denied find: /home/michael/initramfs-source/opt: Permission denied find: /home/michael/initramfs-source/root: Permission denied make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 make[1]: *** [usr] Error 2 make[1]: *** Waiting for unfinished jobs.... make[1]: *** wait: No child processes.

2007-05-02kconfig: refer to qt3 if we cannot find qt librariesSam Ravnborg
We do not support qt4 (yet) so the simple fix was to warn that qt3 are missing. The better fix would have been to implment qt4 support but that has failed so far. This solves http://bugzilla.kernel.org/show_bug.cgi?id=8277 Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-02kbuild: handle compressed cpio initramfs-esAlex Landau
Make kbuild handle compressed cpio initramfs-es. An already compressed cpio is copied directly to usr/, while a non-compressed cpio is filtered through gzip (no changes here) on its way to usr/. If the user has created a compressed cpio by other means, this saves him from uncompressing it, just to be compressed again by kbuild.

2007-05-02kbuild/mkuboot.sh: allow spaces in CROSS_COMPILEUwe kleine-König
I'm currently using CROSS_COMPILE="ccache arm-linux-". With that the bash builtin command "type" searches for ccache and arm-linux-mkimage and so sets MKIMAGE="/path/to/ccache" as I don't have arm-linux-mkimage. Then the script dies with an error, that ccache doesn't support the argument -A. This patch adds some quoting such that it works again for me. Please note that this patch doesn't help you if you use ${CROSSCOMPILE}-mkimage and ccache as mkuboot.sh now searches for the command "ccache arm-linux-mkimage".

2007-05-02kbuild: override build timestamp & versionSam Ravnborg
Introduce KBUILD_BUILD_VERSION to make it possible to override kernel build version during build time. Introduce KBUILD_BUILD_TIMESTAMP to make it possible to override kernel build timestamp during build time. But variables are useful mainly by distros that want to pass info from an SCM when building the kernel. Timestamp could be last checkin date for a file etc. The idea came from Olaf Hering <olaf@aepfle.de> Cc: Olaf Hering <olaf@aepfle.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-02kbuild: complain about missing system callsSam Ravnborg
Most system calls seems to get added to i386 first. This patch automatically generates a warning for any new system call which is implemented on i386 but not the architecture currently being compiled. On PowerPC at the moment, for example, it results in these warnings: init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented The file scripts/checksyscalls.sh list a number of legacy system calls that are ignored because they only makes sense on i386 systems.
