2010-04-07x86: Add optimized popcnt variantsBorislav Petkov1-0/+4
Add support for the hardware version of the Hamming weight function, popcnt, present in CPUs which advertize it under CPUID, Function 0x0000_0001_ECX[23]. On CPUs which don't support it, we fallback to the default lib/hweight.c sw versions. A synthetic benchmark comparing popcnt with __sw_hweight64 showed almost a 3x speedup on a F10h machine.

2010-03-13scripts/kernel-doc: fix empty function description sectionRandy Dunlap1-1/+1
scripts/kernel-doc mishandles a function that has a multi-line function short description and no function parameters. The observed problem was from drivers/scsi/scsi_netlink.c: /** * scsi_netlink_init - Called by SCSI subsystem to intialize * the SCSI transport netlink interface * **/ kernel-doc treated the " * " line as a Description: section with only a newline character in the Description contents. This caused output_highlight() to complain: "output_highlight got called with no args?", plus produce a perl call stack backtrace. The fix is just to ignore Description sections if they only contain "\n".

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.

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.

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).

2010-01-17modpost: fix segfault in sym_is() with prefixed archesMike Frysinger1-1/+1
The sym_is() compares a symbol in an attempt to automatically skip symbol prefixes. It does this first by searching the real symbol with the normal unprefixed symbol. But then it uses the length of the original symbol to check the end of the substring instead of the length of the symbol it is looking for. On non-prefixed arches, this is effectively the same thing, so there is no problem. On prefixed-arches, since this is exceeds by just one byte, a crash is rare and it is usually a NUL byte anyways. But every once in a blue moon, you get the right page alignment and it segfaults. For example, on the Blackfin arch, sym_is() will be called with the real symbol "___mod_usb_device_table" as "symbol" when looking for the normal symbol "__mod_usb_device_table" as "name". The substring will thus return one byte into "symbol" and store it into "match". But then "match" will be indexed with the length of "symbol" instead of "name" and so we will exceed the storage. i.e. the code ends up doing: char foo[] = "abc"; return foo[strlen(foo)+1] == '\0'; Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-01-16markup_oops.pl: fix error with x86Hui Zhu1-1/+1
When I try to use markup_oops.pl in x86, I always get: cat 1 | perl markup_oops.pl ./vmlinux objdump: --start-address: bad number: NaN No matching code found This is because in line: if ($line =~ /EIP is at ([a-zA-Z0-9\_]+)\+0x([0-9a-f]+)\/[a-f0-9]/) { $function = $1; $func_offset = $2; } $func_offset will get a number like "0x2" But in follow code: my $decodestart = Math::BigInt->from_hex("0x$target") - Math::BigInt->from_hex("0x$func_offset"); It add other ox to ox2. Then this value will be set to NaN. So I made a small patch to fix it.

2010-01-13kbuild: really fix bzImage build with non-bash shJonathan Nieder1-2/+7
In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh, arch/x86/boot/compressed/vmlinux.bin.lzma ends with '\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and the resulting vmlinuz fails to boot. This improves on the previous behavior, in which the file contained the characters '-ne ' as well, but not by much. Previous commits replaced "echo -ne" first with "/bin/echo -ne", then "printf" in the hope of improving portability, but none of these commands is guaranteed to support hexadecimal escapes on POSIX systems. So use the shell to convert from hexadecimal to octal. With this change, an LZMA-compressed kernel built with dash as sh boots correctly again.

2010-01-11lib: add support for LZO-compressed kernelsAlbin Tonnerre1-0/+5
This patch series adds generic support for creating and extracting LZO-compressed kernel images, as well as support for using such images on the x86 and ARM architectures, and support for creating and using LZO-compressed initrd and initramfs images. Russell King said: : Testing on a Cortex A9 model: : - lzo decompressor is 65% of the time gzip takes to decompress a kernel : - lzo kernel is 9% larger than a gzip kernel : : which I'm happy to say confirms your figures when comparing the two. : : However, when comparing your new gzip code to the old gzip code: : - new is 99% of the size of the old code : - new takes 42% of the time to decompress than the old code : : What this means is that for a proper comparison, the results get even better: : - lzo is 7.5% larger than the old gzip'd kernel image : - lzo takes 28% of the time that the old gzip code took : : So the expense seems definitely worth the effort. The only reason I : can think of ever using gzip would be if you needed the additional : compression (eg, because you have limited flash to store the image.) : : I would argue that the default for ARM should therefore be LZO. This patch: The lzo compressor is worse than gzip at compression, but faster at extraction. Here are some figures for an ARM board I'm working on: Uncompressed size: 3.24Mo gzip 1.61Mo 0.72s lzo 1.75Mo 0.48s So for a compression ratio that is still relatively close to gzip, it's much faster to extract, at least in that case. This part contains: - Makefile routine to support lzo compression - Fixes to the existing lzo compressor so that it can be used in compressed kernels - wrapper around the existing lzo1x_decompress, as it only extracts one block at a time, while we need to extract a whole file here - config dialog for kernel compression [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: cleanup] Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Tested-by: Wu Zhangjin <wuzhangjin@gmail.com> Acked-by: "H.
