2009-12-15scripts/get_maintainer.pl: support multiple VCSs - add mercurialJoe Perches1-93/+168
Restructure a bit for multiple version control systems support. Use a hash for each supported VCS that contains the commands and patterns used to find commits, logs, and signers. --git command line options are still used for hg except for --git-since. Use --hg-since instead. The number of commits can differ for git and hg, so --rolestats might be different. Style changes: Use common push style push(@foo...), simplify a return Bumped version to 0.23.

2009-12-15module: make MODULE_SYMBOL_PREFIX into a CONFIG optionAlan Jenkins4-10/+15
The next commit will require the use of MODULE_SYMBOL_PREFIX in .tmp_exports-asm.S. Currently it is mixed in with C structure definitions in "asm/module.h". Move the definition of this arch option into Kconfig, so it can be easily accessed by any code. This also lets modpost.c use the same definition. Previously modpost relied on a hardcoded list of architectures in mk_elfconfig.c. A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs, showed the generated code was unchanged. vmlinux was identical save for build ids, and an apparently randomized suffix on a single "__key" symbol in the kallsyms data).

2009-12-14microblaze: ftrace: Add dynamic trace supportMichal Simek1-0/+3
With dynamic function tracer, by default, _mcount is defined as an "empty" function, it returns directly without any more action. When enabling it in user-space, it will jump to a real tracing function(ftrace_caller), and do the real job for us. Differ from the static function tracer, dynamic function tracer provides two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the tracing of some indicated kernel functions(set_ftrace_filter). In the kernel version, there is only one "_mcount" string for every kernel function, so, we just need to match this one in mcount_regex of scripts/recordmcount.pl. For more information please look at code and Documentation/trace folder. Steven ACK that scripts/recordmcount.pl part.

2009-12-12kbuild: generate modules.builtinMichal Marek3-1/+82
To make it easier for module-init-tools and scripts like mkinitrd to distinguish builtin and missing modules, install a modules.builtin file listing all builtin modules. This is done by generating an additional config file (tristate.conf) with tristate options set to uppercase 'Y' or 'M'. If we source that config file, the builtin modules appear in obj-Y.

2009-12-12genksyms: properly consider EXPORT_UNUSED_SYMBOL{,_GPL}()Jan Beulich2-94/+99
Despite being unused these should also get a CRC calculated. Primarily I view this as a consistency thing. But I also think this is one of the reasons why __crc_* need to be weak (which I think should be avoided, and hence we should have the goal to eliminate this so that failure to calculate a proper CRC for a symbol causes the build to fail).

The new -B option compresses blank lines around a deleted section so that blank lines around "paragraphs" of code don't get doubled.

2009-12-12kbuild: specify absolute paths for cscopeDaniel Vetter1-1/+7
Cscope doesn't hadle relative paths when cscope.out is not in $PWD. Use absolute paths when generating cscope.files, which seems to be the recommended way to generate cscope.out, anyway (at least according to cscope.sf.net). The speed and size differences are minimal, the only drawback is that the database needs to be regenerated if the source directory is moved.

2009-12-12scripts/package: deb-pkg: use fakeroot if availableJonathan Nieder1-2/+19
Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or becoming root oneself or it errors out. Unless already running as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a good default. With this patch applied, you can run "make oldconfig deb-pkg" as an ordinary user to build a binary package for an updated kernel tree and it should just work. fakeroot is too zealous by default in treating files as owned by root. Its wrapped stat() sets st_uid and st_gid to 0 for all files, which causes Git to go on a wild goose chase if CONFIG_LOCALVERSION_AUTO is set, checking if any file's content has changed along with its stat information. Avoid this by telling fakeroot to use the actual owner and group for preexisting files, by passing it the -u option.

2009-12-12scripts/package: add KBUILD_PKG_ROOTCMD variableJonathan Nieder1-1/+2
Let the deb-pkg target acquire (fake) root privileges before running commands that need them. Without such privileges, deb-pkg errors out because chown fails. The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a command to run other commands with possibly fake elevated privileges. Since this is not needed for the tar-pkg and rpm-pkg targets, it is only used by deb-pkg. If it is not defined, the behavior is as before, and the user will have to rerun make as root. In other words, as a shortcut, instead of running 'make oldconfig && make && fakeroot -u make deb-pkg', one can use the single command 'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

2009-12-12scripts/package: tar-pkg: use tar --owner=rootMichal Marek1-1/+5
Use the --owner= and --group= options to make sure the entries in the built tar file are owned by root. Without this change, a careless sysadmin using the tar-pkg target can easily end up installing a kernel that is writable by the unprivileged user account used to build the kernel. Test that these options are understood before using them so that non-GNU versions of tar can still be used if the operator is appropriately cautious.

2009-12-11USB: handle bcd incrementation in usb modalias generationNathaniel McCallum1-2/+47
This patch fixes a bug when incrementing/decrementing on a BCD formatted integer (i.e. 0x09++ should be 0x10 not 0x0A).

2009-12-11USB: add hex/bcd detection to usb modalias generationNathaniel McCallum1-12/+36
The current code to generate usb modaliases from usb_device_id assumes that the device's bcdDevice descriptor will actually be in BCD format. While this should be a sane assumption, some devices don't follow spec and just use plain old hex. This causes drivers for these devices to generate invalid modalias lines which will never actually match for the hardware. The following patch adds hex support for bcdDevice in file2alias.c by detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and adjusts the output to hex format accordingly. Drivers for devices which have bcdDevice conforming to BCD will have no change in modalias output. Drivers for devices which don't conform (i.e. ibmcam) should now generate valid modaliases.

2009-12-02tracing: Add DEFINE_EVENT(), DEFINE_SINGLE_EVENT() support to docbookJason Baron1-3/+12
The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook style comments that used to live with 'TRACE_EVENT()' are now moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook system understand the new 'DEFINE_EVENT()' macro. In addition I've tried to futureproof the patch, by also adding support for 'DEFINE_SINGLE_EVENT()', since there has been discussion about renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT(). Without this patch the tracepoint docbook fails to build. I've verified that this patch correctly builds the tracepoint docbook which currently covers signals, and irqs.

2009-11-17tracing: Only print objcopy version warning once from recordmcountSteven Rostedt1-2/+10
If the user has an older version of objcopy, that can not handle converting local symbols to global and vice versa, then some functions will not be part of the dynamic function tracer. The current code in recordmcount.pl will print a warning in this case. Unfortunately, there exists lots of files that may have this issue with older objcopys and this will cause a warning for every file compiled with this issue. This patch solves this overwhelming output by creating a .tmp_quiet_recordmcount file on the first instance the warning is encountered. The warning will not print if this file exists. The temp file is deleted at the beginning of the compile to ensure that the warning will happen once again on new compiles (because the issue is still present).

2009-11-16dtc: Set "noinput" in the lexer to avoid an unused functionJosh Triplett2-17/+54
Regenerate the corresponding generated lexer. Regenerating the lexer with current flex also provides prototypes for various yy* functions, making some -Wmissing-prototypes warnings go away as well. Signed-off-by: Josh Triplett <josh@joshtriplett.org>
2009-11-16genksyms: Mark is_reserved_word staticJosh Triplett2-45/+52
The genksyms keyword gperf hash provides a function is_reserved_word. genksyms #includes the resulting generated file keywords.c, so the function gets used only in the same source file that defines it. Mark is_reserved_word static, and regenerate the corresponding generated file. Signed-off-by: Josh Triplett <josh@joshtriplett.org>

kconfig's keyword hash, lexer, and parser define various functions used only locally. Declare these functions as static, and regenerate the corresponding generated files. Signed-off-by: Josh Triplett <josh@joshtriplett.org>

2009-10-29tracing: Exit with error if a weak function is used in recordmcount.plLi Hong1-7/+3
If a weak function is used as a relocation reference for mcount callers and that function is overridden, it will cause ftrace to fail at run time. The current code should prevent a weak function from being used, but if one is, the code should exit with an error to fail at compile time.

2009-10-29tracing: Move conditional into update_funcs() in recordmcount.plLi Hong1-5/+3
Move all the condition validations into the function update_funcs(). Also update_funcs should not die if $ref_func is undefined for there may be more than one valid section in an object file.

2009-10-29tracing: Add regex for weak functions in recordmcount.plLi Hong1-7/+9
Add a variable to contain the regex needed to find weak functions in the 'nm' output. This will allow other archs to easily override it. Also rename the regex variable $nm_regex to $local_regex to be more descriptive.

2009-10-29tracing: Move mcount section search to front of loop in recordmcount.plLi Hong1-14/+18
Move the mcount section check to the beginning of the objdump read loop. This makes the code easier to follow since the search for the mcount section is performed first before the mcount callers are processed.

2009-10-29tracing: Fix objcopy revision check in recordmcount.plLi Hong1-29/+27
The current logic to check objcopy's version is incorrect. This patch fixes the algorithm and disables the use of local functions as a reference if the objcopy version does not support static to global conversions. Also remove some usused variables.

2009-10-29tracing: Check absolute path of input file in recordmcount.plLi Hong1-1/+1
The ftrace.c file may reference the mcount function and this may interfere with the recordmcount.pl processing. To avoid this, the code does not process the kernel/trace/ftrace.o. But currently the check is against a relative path. This patch modifies the check to succeed if the path is an absolute path.

2009-10-29tracing: Amend documentation in recordmcount.pl to reflect implementationLi Hong1-35/+49
The documentation currently says we will use the first function in a section as a reference. The actual algorithm is: choose the first global function we meet as a reference. If there is none, choose the first local one. Change the documentation to be consistent with the code. Also add several other clarifications.

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.
