* kbuild: strip generated symbols from *.koJan Beulich2008-12-19
| | | | | | | | | | | | | | | | | | | | | This patch changes the way __crc_ symbols are being resolved from using ld to do so to using the assembler, thus allowing these symbols to be marked local (the linker creates then as global ones) and hence allow stripping (for modules) or ignoring (for vmlinux) them. While at this, also strip other generated symbols during module installation. One potentially debatable point is the handling of the flags passeed to gcc when translating the intermediate assembly file into an object: passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to gas whenever is sees any -g* option, even for -g0, and despite the fact that the compiler would have already produced all necessary debug info in the C->assembly translation phase. I took the approach of just filtering out all -g* options, but an alternative to such negative filtering might be to have a positive filter which might, in the ideal case allow just all the -Wa,* options to pass through.

* scripts: improve the decodecode scriptArjan van de Ven2008-12-03
| | | | | | | | | | | | | | | | | | | | | | | | kerneloops.org has been using an improved "decodecode" script, specifically it has a special marker that shows which line in the assembly the oops happened at, like this: 20: 83 e0 03 and $0x3,%eax 23: 09 d8 or %ebx,%eax 25: 85 db test %ebx,%ebx 27: 89 02 mov %eax,(%edx) 29: 74 0f je 0x3a 2b:* 3b 73 04 cmp 0x4(%ebx),%esi <-- trapping instruction 2e: 75 05 jne 0x35 30: 89 53 04 mov %edx,0x4(%ebx) 33: eb 07 jmp 0x3c 35: 89 53 08 mov %edx,0x8(%ebx) this patch updates the kernel copy to also have this functionality.

* genksyms: allow to ignore symbol checksum changesAndreas Gruenbacher2008-12-03
| | | | | | | | | | | | | | | | | | | | | This adds an "override" keyword for use in *.symvers / *.symref files. When a symbol is overridden, the symbol's old definition will be used for computing checksums instead of the new one, preserving the previous checksum. (Genksyms will still warn about the change.) This is meant to allow distributions to hide minor actual as well as fake ABI changes. (For example, when extra type information becomes available because additional headers are included, this may change checksums even though none of the types used have actully changed.) This approach also allows to get rid of "#ifdef __GENKSYMS__" hacks in the code, which are currently used in some vendor kernels to work around checksum changes.

* genksyms: track symbol checksum changesAndreas Gruenbacher2008-12-03
| | | | | | | | | | | | | | | | | | | | | | | | Sometimes it is preferable to avoid changes of exported symbol checksums (to avoid breaking externally provided modules). When a checksum change occurs, it can be hard to figure out what caused this change: underlying types may have changed, or additional type information may simply have become available at the point where a symbol is exported. Add a new --reference option to genksyms which allows it to report why checksums change, based on the type information dumps it creates with the --dump-types flag. Genksyms will read in such a dump from a previous run, and report which symbols have changed (and why). The behavior can be controlled for an entire build as follows: If KBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes dump files. If any *.symref files exist, those will be used as the reference to check against. If KBUILD_PRESERVE is set, checksum changes will fail the build.

* kbuild: fix -I option expansion with O=... buildsSam Ravnborg2008-12-03
| | | | | | | | | | | | | | | | | | | When adding extra -I options with O=... we could end up in a situation where there were no parameters to -I. So we had a commandline that looked like this: ... -I -Wall ... This had the undesired side effect that gcc assumed "-Wall" was a path to look for include files so this options was effectively ignored. This happens only when we build the generated module.mod.c files as part of the final modules builds and is as such harmless with current kbuild. This bug was exposed when we rearranged the options to gcc. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

* Fix incompatibility with versions of Perl less than 5.6.0Jeremy Huntwork2008-10-29
| | | | | | | | | | | | | | | | | | Fix headers_install.pl and headers_check.pl to be compatible with versions of Perl less than 5.6.0. It has been tested with Perl 5.005_03 and 5.8.8. I realize this may not be an issue for most people, but there will still be some that hit it, I imagine. There are three basic issues: 1. Prior to 5.6.0 open() only used 2 arguments, and the versions of the scripts in 2.6.27.1 use 3. 2. 5.6.0 also introduced the ability to use uninitialized scalar variables as file handles, which the current scripts make use of. 3. Lastly, 5.6.0 also introduced the pragma 'use warnings'. We can use the -w switch and be backwards compatible.

* kbuild: tag with git revision when git describe is missingTrent Piepho2008-10-29
| | | | | | | | | | | | | | | | | | setlocalversion used to use an abbreviated git commit sha1 to generate the tag. This was changed in commit d882421f4e08ddf0a94245cdbe516db260aa6f41 "kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish format" to use git describe to come up with a tag. Which is nice, but git describe sometimes can't describe the revision. Commit 56b2f0706d82535fd8d85503f2dcc0be40c8e55d ("setlocalversion: do not describe if there is nothing to describe") addressed this, but there is still no tag generated.

Breakage had been introduced when conf_set_all_new_symbols() got used for allmodconfig et.al. What happens is that sym_calc_value(modules_sym) done in conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES. When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER] on everything, but it has no effect on sym->curr for the symbols that already have SYMBOL_VALID - these are stuck. Solution: use sym_clear_all_valid() in there. Note that it makes reevaluation of modules_sym redundant - sym_clear_all_valid() will do that itself.

| * tracing/fastboot: fix initcalls disposition in bootgraph.plFrederic Weisbecker2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | When bootgraph.pl parses a file, it gives one row for each initcall's pid. But only few of them will be displayed => the longest. This patch corrects it by giving only a rows for pids which have initcalls that will be displayed.

| * tracing/fastboot: fix bootgraph.pl initcall name regexpArnaud Patard2008-10-14
| | | | | | | | | | | | | | | | | | The regexp used to match the start and the end of an initcall are matching only on [a-zA-Z\_]. This rules out initcalls with a number in them. This patch is fixing that. Signed-off-by: Arnaud Patard <apatard@mandriva.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * tracing/fastboot: fix issues and improve output of bootgraph.plArjan van de Ven2008-10-14
| | | | | | | | | | | | | | | | | | | | David Sanders reported some issues with bootgraph.pl's display of his sytems bootup; this commit fixes these by scaling the graph not from 0 - end time but from the first initcall to the end time; the minimum display size etc also now need to scale with this, as does the axis display.

| * tracing/fastboot: add a script to visualize the kernel boot process / timeArjan van de Ven2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When optimizing the kernel boot time, it's very valuable to visualize what is going on at which time. In addition, with the fastboot asynchronous initcall level, it's very valuable to see which initcall gets run where and when. This patch adds a script to turn a dmesg into a SVG graph (that can be shown with tools such as InkScape, Gimp or Firefox) and a small change to the initcall code to print the PID of the thread calling the initcall (so that the script can work out the parallelism).
