* checkpatch: fix false EXPORT_SYMBOL warningAndy Whitcroft2009-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | Ingo reported that the following lines triggered a false warning, static struct lock_class_key rcu_lock_key; struct lockdep_map rcu_lock_map = STATIC_LOCKDEP_MAP_INIT("rcu_read_lock", &rcu_lock_key); EXPORT_SYMBOL_GPL(rcu_lock_map); from kernel/rcutree.c , and the false warning looked like this, WARNING: EXPORT_SYMBOL(foo); should immediately follow its function/variable +EXPORT_SYMBOL_GPL(rcu_lock_map); We actually should be checking the statement before the EXPORT_* for a mention of the exported object, and complain where it is not there.

* checkpatch: fix __attribute__ matchingAndy Whitcroft2009-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the following code, union thread_union init_thread_union __attribute__((__section__(".data.init_task"))) = { INIT_THREAD_INFO(init_task) }; There is a non-conforming declaration. It should really be like the following, union thread_union init_thread_union __attribute__((__section__(".data.init_task"))) = { INIT_THREAD_INFO(init_task) }; However, checkpatch doesn't catch this right now because it doesn't correctly evaluate the "__attribute__". It is not at all clear that we care what preceeds an assignment style attribute when we find the open brace. Relax the test so we do not need to check the __attribute__.

* checkpatch: fix false errors due to macro concatenationAndy Whitcroft2009-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | The macro concatenation (##) sequence can cause false errors when checking macro's. Checkpatch doesn't currently know about the operator. For example this line, + entry = (struct ftrace_raw_##call *)raw_data; \ is correct but it produces the following error, ERROR: need consistent spacing around '*' (ctx:WxB) + entry = (struct ftrace_raw_##call *)raw_data;\ ^ The line above doesn't have any spacing problems, and if you remove the macro concatenation sequence checkpatch doesn't give any errors. Extend identifier handling to include ## concatenation within the definition of an identifier.

| * kbuild: Don't define ALIGN and ENTRY when preprocessing linker scripts.Tim Abbott2009-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding a reference to <linux/linkage.h> to x86's <asm/cache.h> causes the x86 linker script to have syntax errors, because the ALIGN and ENTRY keywords get redefined to the assembly implementations of those. One could fix this by adjusting the include structure, but I think any solution based on that approach would be fragile. Currently, it is impossible when writing a header to do something different for assembly files and linker scripts, even though there are clearly cases where one wants them to define macros differently for the two (ENTRY being an excellent example). So I think the right solution here is to introduce a new preprocessor definition, called LINKER_SCRIPT that is set along with __ASSEMBLY__ for linker scripts, and to use that to not define ALIGN and ENTRY in linker scripts. I suspect we'll find other uses for this mechanism in the future. Signed-off-by: Tim Abbott <tabbott@ksplice.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

Disabling the enable_search property does not mean that search is not possible, it only disables the typeahead; to execute a search in the treeview, you can just call it up explicitly (i.e.: on most systems that will be Ctrl-f).

First: The identifier-list miss the DEFINE_TRACE,EXPORT_TRACEPOINT_SYMBOL,EXPORT_TRACEPOINT_SYMBOL_GPL special handling, which can result in a wrong tag, not to jump to the right variable definition or function implementation. Second: It makes no real sense to include function prototypes and external and forward variable declarations, because jumping to a tag will sometimes go to this and not to the real definition and implementation. The information about the declaration is still there at the definition and implementation place. So this patch make it lot easier to navigate through the kernel source tree using vi.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch spi drivers can use standard spi_driver.id_table and MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like we do with I2C drivers. This is useful when a single driver supports several variants of devices but it is not possible to detect them in run-time (like non-JEDEC chips probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is overkill. This patch also makes life a lot easier on OpenFirmware platforms, since with OF we extensively use proper device IDs in modaliases.

* | kallsyms: fix segfault in prefix_underscores_count()Paul Mundt2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b478b782e110fdb4135caa3062b6d687e989d994 "kallsyms, tracing: output more proper symbol name" introduces a "bugfix" that introduces a segfault in kallsyms in my configurations. The cause is the introduction of prefix_underscores_count() which attempts to count underscores, even in symbols that do not have them. As a result, it just uselessly runs past the end of the buffer until it crashes: CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 KSYM .tmp_kallsyms1.S /bin/sh: line 1: 16934 Done sh-linux-gnu-nm -n .tmp_vmlinux1 16935 Segmentation fault | scripts/kallsyms > .tmp_kallsyms1.S make: *** [.tmp_kallsyms1.S] Error 139 This simplifies the logic and just does a straightforward count.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add checks for Blackfin-specific issues that seem to crop up from time to time. In particular, we have helper macros to break a 32bit address into the hi/lo parts, and we want to make sure people use the csync/ssync variant that includes fun anomaly workarounds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: - More verbose help/usage message. - Make the option -f an alias for --file. - On -h, --help, and --version display help message and exit(0). - With no FILE(s) given, exit(1) with "no input files". - On invalid options display help/usage and exit(1).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the sanitation process in checkpatch.pl so that it blocks out the text after a C99 style comment the same way it does with block style comments. This prevents the text from getting processed as regular code.
