2 | * linux/fs/proc/array.c | |
3 | * | |
4 | * Copyright (C) 1992 by Linus Torvalds | |
5 | * based on ideas by Darren Senn | |
6 | * | |
7 | * Fixes: | |
8 | * Michael. K. Johnson: stat,statm extensions. | |
9 | * <johnsonm@stolaf.edu> | |
10 | * | |
11 | * Pauline Middelink : Made cmdline,envline only break at '\0's, to | |
12 | * make sure SET_PROCTITLE works. Also removed | |
13 | * bad '!' which forced address recalculation for | |
14 | * EVERY character on the current page. | |
15 | * <middelin@polyware.iaf.nl> | |
16 | * | |
17 | * Danny ter Haar : added cpuinfo | |
18 | * <dth@cistron.nl> | |
19 | * | |
20 | * Alessandro Rubini : profile extension. | |
21 | * <rubini@ipvvis.unipv.it> | |
22 | * | |
23 | * Jeff Tranter : added BogoMips field to cpuinfo | |
24 | * <Jeff_Tranter@Mitel.COM> | |
25 | * | |
26 | * Bruno Haible : remove 4K limit for the maps file | |
27 | * <haible@ma2s2.mathematik.uni-karlsruhe.de> | |
28 | * | |
29 | * Yves Arrouye : remove removal of trailing spaces in get_array. | |
30 | * <Yves.Arrouye@marin.fdn.fr> | |
31 | * | |
32 | * Jerome Forissier : added per-CPU time information to /proc/stat | |
33 | * and /proc/<pid>/cpu extension | |
34 | * <forissier@isia.cma.fr> | |
35 | * - Incorporation and non-SMP safe operation | |
36 | * of forissier patch in 2.1.78 by | |
37 | * Hans Marcus <crowbar@concepts.nl> | |
38 | * | |
39 | * aeb@cwi.nl : /proc/partitions | |
40 | * | |
41 | * | |
42 | * Alan Cox : security fixes. | |
526719ba | 43 | * <alan@lxorguk.ukuu.org.uk> |
1da177e4 LT |
44 | * |
45 | * Al Viro : safe handling of mm_struct | |
46 | * | |
47 | * Gerhard Wichert : added BIGMEM support | |
48 | * Siemens AG <Gerhard.Wichert@pdb.siemens.de> | |
49 | * | |
50 | * Al Viro & Jeff Garzik : moved most of the thing into base.c and | |
51 | * : proc_misc.c. The rest may eventually go into | |
52 | * : base.c too. | |
