2010-03-08Revert "kbuild: specify absolute paths for cscope"Michal Marek1-7/+3

Given that absolute paths can be forced by make O=. cscope, change the default back to relative paths.

2010-03-06checkpatch.pl: add union and struct to the exceptions listStefani Seibold1-0/+2
Here is a small code snippet, which will be complained about by checkpatch.pl: #define __STRUCT_KFIFO_COMMON(recsize, ptrtype) \ union { \ struct { \ unsigned int in; \ unsigned int out; \ }; \ char rectype[recsize]; \ ptrtype *ptr; \ const ptrtype *ptr_const; \ }; This construct is legal and safe, so checkpatch.pl should accept this. It should be also true for struct defined in a macro. Add the `struct' and `union' keywords to the exceptions list of the checkpatch.pl script, to prevent error message "Macros with multiple statements should be enclosed in a do - while loop". Otherwise it is not possible to build a struct or union with a macro.

2010-03-06scripts/get_maintainer.pl: add --file-emails, find embedded email addressesJoe Perches1-7/+76
Add an imperfect option to search a source file for email addresses. New option: --file-emails or --fe email addresses in files are freeform text and are nearly impossible to parse. Still, might as well try to do a somewhat acceptable job of finding them. This code should find all addresses that are in the form addr@domain.tld The code assumes that up to 3 alphabetic words along with dashes, commas, and periods that preceed the email address are a name. If 3 words are found for the name, and one of the first two words are a single letter and period, or just a single letter then the 3 words are use as name otherwise the last 2 words are used. Some variants that are shown correctly: John Smith <jksmith@domain.org> Random J. Developer <rjd@tld.com> Random J. Developer (rjd@tld.com) J. Random Developer rjd@tld.com Variants that are shown nominally correctly: Written by First Last (funny-addr@somecompany.com) is shown as: First Last <funny-addr@somecompany.com> Variants that are shown incorrectly: Some Really Long Name <srln@foo.bar> MontaVista Software, Inc. <source@mvista.com> are returned as: Long Name <srln@foo.bar> "Software, Inc" <source@mvista.com> --roles and --rolestats show "(in file)" for matches. For instance: Without -file-emails: $ ./scripts/get_maintainer.pl -f -nogit -roles net/core/netpoll.c David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL]) linux-kernel@vger.kernel.org (open list) With -fe: $ ./scripts/get_maintainer.pl -f -fe -nogit -roles net/core/netpoll.c David S.

2010-02-26kernel-doc: track line numbers for each file separatelyIlya Dryomov1-0/+2
The problem is that $. keeps track of the current record number (which is line number by default). But if you pass it multiple files, it does not wrap at the end of file, and therefore contains the *total* number of processed lines. I suppose we can fix line numbering by introducing a simple assignment $. = 1 before processing every new file.

Currently looking up a structure definition in TAGS / tags takes one to one of multiple "static struct X" definitions in arch sources, which makes it for many structs practically impossible to get to the required header. This patch changes the order of sources being tagged to first scan architecture includes, then the top-level include/ directory, and only then the rest. It also takes into account, that many architectures have more than one include directory, i.e., not only arch/$ARCH/include, but also arch/$ARCH/mach-X/include etc. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Reviewed-by: WANG Cong <xiyou.wangcong@gmail.com> [mmarek@suse.cz: fix 'var+=text' bashism] Signed-off-by: Michal Marek <mmarek@suse.cz>

2010-02-02kconfig: Add LSMOD=file to override the lsmod for localmodconfigSteven Rostedt2-13/+38
Doing the following: make LSMOD=file localmodconfig Will make the streamline-config code use the given file instead of lsmod. If the file is an executable, it will execute it, otherwise it will read it as text. make LSMOD=/my/local/path/lsmod localmodconfig The above will execute the lsmod in /my/local/path instead of the lsmods that may be located elsewhere. make LSMOD=embedded_board_lsmod localmodconfig The above will read the "embedded_board_lsmod" as a text file. This is useful if you are doing a cross compile and need to run the config against modules that exist on an embedded device. Note, if the LSMOD= file does is not a path, it will add the path to the object directory. That is, the above example will look for "embedded_board_lsmod" in the directory that the binary will be built in (the O=dir directory).

When I use markup_oops.pl parse a x8664 oops, I got: objdump: --start-address: bad number: NaN No matching code found This is because: main::(./m.pl:228): open(FILE, "objdump -dS --adjust-vma=$vmaoffset --start-address=$decodestart --stop-address=$decodestop $filename |") || die "Cannot start objdump"; DB<3> p $decodestart NaN This NaN is from: main::(./m.pl:176): my $decodestart = Math::BigInt->from_hex("0x$target") - Math::BigInt->from_hex("0x$func_offset"); DB<2> p $func_offset 0x175 There is already a "0x" in $func_offset, another 0x makes it a NaN. The $func_offset is from line: if ($line =~ /RIP: 0010:\[\<[0-9a-f]+\>\] \[\<[0-9a-f]+\>\] ([a-zA-Z0-9\_]+)\+(0x[0-9a-f]+)\/0x[a-f0-9]/) { $function = $1; $func_offset = $2; } I make a patch to change "(0x[0-9a-f]+)\/0x[a-f0-9]/)" to "0x([0-9a-f]+)\/0x[a-f0-9]/)".

2010-02-02get_maintainer.pl: teach git log to use --no-colorRichard Kennedy1-2/+2
When git has been set to always use color in .gitconfig then I get the warning message Bad divisor in main::vcs_assign: 0 This is caused by vcs_file_signoffs not matching any commits due to the pattern not understand the colour codes. Fix this by telling git log to never use colour.

2010-02-02kconfig: Look in both /bin and /sbin for lsmod in streamline_config.plSteven Rostedt1-1/+14
Distributions now have lsmod in /bin instead of /sbin. But to handle both cases, we look for it in /sbin /bin /usr/bin and /usr/sbin. If lsmod is not found in any of those paths, it defaults to use just lsmod and hopes that it lies in the path of the user.

2010-02-02scripts: use %_tmppath in "make rpm-pkg"John Saalwaechter1-1/+1
The mkspec script hardcodes "/var/tmp" into the generated rpm spec file's BuildRoot. The user, however, may have a custom setting for %_tmppath, which should be used in BuildRoot. This patch changes mkspec's BuildRoot output to appropriately use %_tmppath. Signed-off-by: John Saalwaechter <saalwaechter@gmail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>

2010-02-02scripts: change scripts to use system python instead of envDon Zickus2-2/+2
Just a small change to a couple of scripts to go from #!/usr/bin/env python to #!/usr/bin/python This shouldn't effect anyone, unless they don't install python there. In preparation for python3, Fedora is doing a big push to change the scripts to use the system python. This allows developers to put the python3 in their path without fear of breaking existing scripts. Now I am pretty sure anyone using python3 for testing purposes will probably not run any of the scripts I changed, but Fedora has this automated tool that checks for this stuff so I thought I would try to push it upstream.

2010-02-02scripts/kallsyms: suppress build warningHimanshu Chauhan1-2/+4
Suppress a warn_unused_result warning. fgets is called as a part of error handling. It is called just to drop a line and return immediately. read_map is reading the file in a loop and read_symbol reads line by line. So I think there is no point in using return value for useful checking. Other checks like 3 items were returned or !EOF have already been done.

2010-02-02Improve kconfig symbol hashingAndi Kleen4-17/+21
While looking for something else I noticed that the symbol hash function used by kconfig is quite poor. It doesn't use any of the standard hash techniques but simply adds up the string and then uses power of two masking, which is both known to perform poorly. The current x86 kconfig has over 7000 symbols. When I instrumented it showed that the minimum hash chain length was 16 and a significant number of them was over 30. It didn't help that the hash table size was only 256 buckets. This patch increases the hash table size to a larger prime and switches to a FNV32 hash. I played around with a couple of hash functions, but that one seemed to perform best with reasonable hash table sizes. Increasing the hash table size even further didn't seem like a good idea, because there are a couple of global walks which walk the complete hash table. I also moved the unnamed bucket to 0. It's still the longest of all the buckets (44 entries), but hopefully it's not often hit except for the global walk which doesn't care. The result is a much nicer distribution: (first column bucket length, second number of buckets with that length) 1: 3505 2: 1236 3: 294 4: 52 5: 3 47: 1 <--- this is the unnamed symbols bucket There are still some 5+ buckets, but increasing the hash table even more would be likely not worth it. This also cleans up the code slightly by removing hard coded magic numbers. I didn't notice a big performance difference either way on my Nehalem system, but I presume it'll help somewhat on slower systems.
