2013-11-07perf tools: Fix version when building out of treeDavid Ahern
When building perf out of tree: $ make perf-tar-src-pkg $ tar -xf perf-<ver>.tar -C /tmp $ cd /tmp/perf<ver> $ make -C tools/perf you get this warning message: make[1]: *** No rule to make target `kernelversion'. Stop. Fix it by saving the perf version in the tar file and using that for the out of tree builds. v2: removed short form request and fixed up version string from usual output.

Andi's change in e0f244c63fc9 ("asmlinkage, module: Make ksymtab and kcrctab symbols and __this_module __visible") make the crc appear first in the symbol table. modpost creates an entry when it sees the CRC, then when it sees the actual symbol, it complains that it's seen it before.

Error When scripts/kernel-doc cannot understand a function prototype, it had been generating a fatal error and stopping immediately. Make this a Warning instead of an Error and keep going. Note that this can happen if the kernel-doc notation that is being parsed is not actually a function prototype; maybe it's a struct or something else, so I added "function" to the warning message to try to make it clearer that scripts/kernel-doc is looking for a function prototype here.

2013-11-05recordmcount.pl: Add support for __fentry__Jamie Iles
With gcc 4.6.0 the -mfentry feature places the function profiling call at the start of the function. When this is used, the call is to __fentry__ and not mcount. This is required for Ksplice as the C version of recordmcount doesn't insert section symbols for the __mcount_loc section so we fall back to the perl version.

2013-11-02scripts/kallsyms: filter symbols not in kernel address spaceMing Lei
This patch uses CONFIG_PAGE_OFFSET to filter symbols which are not in kernel address space because these symbols are generally for generating code purpose and can't be run at kernel mode, so we needn't keep them in /proc/kallsyms. For example, on ARM there are some symbols which may be linked in relocatable code section, then perf can't parse symbols any more from /proc/kallsyms, this patch fixes the problem (introduced b9b32bf70f2fb710b07c94e13afbc729afe221da) Cc: Russell King <linux@arm.linux.org.uk> Cc: linux-arm-kernel@lists.infradead.org Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: stable@vger.kernel.org

Currently the qconf program invoked by 'make xconfig' stores GUI settings in the file ~/.config/Unknown\ Organization.conf.

2013-09-23modpost: Optionally ignore secondary errors seen if a single module build failsGuenter Roeck
Commit ea4054a23 (modpost: handle huge numbers of modules) added support for building a large number of modules. Unfortunately, the commit changed the semantics of the makefile: Instead of passing only existing object files to modpost, make now passes all expected object files. If make was started with option -i, this results in a modpost error if a single file failed to build. Example with the current btrfs build falure on m68k: fs/btrfs/btrfs.o: No such file or directory make[1]: [__modpost] Error 1 (ignored) This error is followed by lots of errors such as: m68k-linux-gcc: error: arch/m68k/emu/nfcon.mod.c: No such file or directory m68k-linux-gcc: fatal error: no input files compilation terminated. make[1]: [arch/m68k/emu/nfcon.mod.o] Error 1 (ignored) This doesn't matter much for normal builds, but it is annoying for builds started with "make -i" due to the large number of secondary errors. Those errors unnececessarily clog any error log and make it difficult to find the real errors in the build. Fix the problem by adding a new parameter '-n' to modpost. If this parameter is specified, modpost reports but ignores missing object files. With this patch, error output from above problem is (with make -i): m68k-linux-ld: cannot find fs/btrfs/ioctl.o: No such file or directory make[2]: [fs/btrfs/btrfs.o] Error 1 (ignored) ... fs/btrfs/btrfs.o: No such file or directory (ignored) Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Michael Marek <mmarek@suse.cz> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2013-09-11checkpatch: add test for positional misuse of section specifiers like __initdataJoe Perches
As discussed recently on the arm [1] and lm-sensors [2] lists, it is possible to use section markers on variables in a way which gcc doesn't understand (or at least not the way the developer intended): static struct __initdata samsung_pll_clock exynos4_plls[nr_plls] = { does NOT put exynos4_plls in the .initdata section. The __initdata marker can be virtually anywhere on the line, EXCEPT right after "struct". The preferred location is before the "=" sign if there is one, or before the trailing ";" otherwise.

2013-09-11checkpatch: reduce runtime/cpu time usedJoe Perches
There are some cases where checkpatch can take a long time to complete. Reduce the likelihood of this long run-time by adding a new test for lines with and without comments and eliminating checks on lines with only comments. This reduces the number of "ctx_statement_block" calls, and also the number of tests of $stat, which is now undefined for these blank lines. One test in particular, the "check for switch/default statements without a break", could take an extremely long time to parse as it tries to skip interleaving comments within the ctx_statement_block/$stat and that could be done multiple times unnecessarily. A small test case taken from cfg80211.h before this patch would take 1000's of seconds to run, now it's just a couple seconds.

It was erroring out on fairly random lines most commonly with messages like: Nested quantifiers in regex; marked by <--HERE in m/(\((?:[^\(\)]++ <-- HERE |(?-1))*\))/ at ./checkpatch.pl line 340. The bug reporter was running a version of perl 5.8 which was end-of-lifed in 2008: http://www.cpan.org/src/. Versions of perl this old are at _best_ quite untested. At worst, they are crusty and known to be completely broken. If folks have a system _that_ old, then we should have mercy on them and give them a half-decent error message rather than fail with nutty error messages. This patch enforces that checkpatch.pl is run with perl 5.10, which was end-of-lifed in 2009. The new --ignore-perl-version command-line switch will let folks override this if they want.

2013-09-05kconfig: do not allow more than one symbol to have 'option modules'Yann E. MORIN
Previously, it was possible to have more than one symbol with the 'option modules' attached to them, although only the last one would in fact control tristates. Since this does not make much sense, only allow at most one symbol to control tristates. Note: it is still possible to have more than one symbol that control tristates, but indirectly: config MOD1 bool "mod1" select MODULES config MOD2 bool "mod2" select MODULES config MODULES bool option modules Signed-off-by: "Yann E.

2013-09-05kconfig: do not special-case 'MODULES' symbolYann E. MORIN
Currently, the 'MODULES' symbol is hard-coded to be the default symbol that enables/disables tristates, if no other symbol was declared with 'option modules'. While this used to be needed for the Linux kernel, we now have an explicit 'option modules' attached to the 'MODULES' symbol (since cset 11097a036), so we no longer need to special-case it in the kconfig code. Furthermore, kconfig is extensively used out of the Linux kernel, and other projects may have another meaning for a symbol named 'MODULES'. This patch changes the way we enable/disable tristates: if a symbol was found with 'option modules' attached to it, then that symbol controls enabling tristates. Otherwise, tristates are disabled, even if a symbol named 'MODULES' exists. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
