x86: convert cpuinfo_x86 array to a per_cpu array
[wrt350n-kernel.git] / fs / proc / proc_misc.c

2 * linux/fs/proc/proc_misc.c
3 *
4 * linux/fs/proc/array.c
5 * Copyright (C) 1992 by Linus Torvalds
6 * based on ideas by Darren Senn
7 *
8 * This used to be the part of array.c. See the rest of history and credits
9 * there. I took this into a separate file and switched the thing to generic
10 * proc_file_inode_operations, leaving in array.c only per-process stuff.
11 * Inumbers allocation made dynamic (via create_proc_entry()). AV, May 1999.

13 * Changes:
