2# Script to apply kernel patches.
3# usage: patch-kernel [ sourcedir [ patchdir [ stopversion ] [ -acxx ] ] ]
4# The source directory defaults to /usr/src/linux, and the patch
5# directory defaults to the current directory.
6# e.g.
7# scripts/patch-kernel . ..
8# Update the kernel tree in the current directory using patches in the
9# directory above to the latest Linus kernel
10# scripts/patch-kernel . .. -ac
11# Get the latest Linux kernel and patch it with the latest ac patch
12# scripts/patch-kernel . .. 2.4.9
13# Gets standard kernel 2.4.9
14# scripts/patch-kernel . .. 2.4.9 -ac
15# Gets 2.4.9 with latest ac patches
16# scripts/patch-kernel . .. 2.4.9 -ac11
17# Gets 2.4.9 with ac patch ac11
18# Note: It uses the patches relative to the Linus kernels, not the
19# ac to ac relative patches
20#
21# It determines the current kernel version from the top-level Makefile.
22# It then looks for patches for the next sublevel in the patch directory.
23# This is applied using "patch -p1 -s" from within the kernel directory.
24# A check is then made for "*.rej" files to see if the patch was
25# successful. If it is, then all of the "*.orig" files are removed.

27# Nick Holloway <Nick.Holloway@alfie.demon.co.uk>, 2nd January 1995.
28#
29# Added support for handling multiple types of compression. What includes
30# gzip, bzip, bzip2, zip, compress, and plaintext.
31#
32# Adam Sulmicki <adam@cfar.umd.edu>, 1st January 1997.
33#
34# Added ability to stop at a given version number
35# Put the full version number (i.e. 2.3.31) as the last parameter
36# Dave Gilbert <linux@treblig.org>, 11th December 1999.
37
38# Fixed previous patch so that if we are already at the correct version
39# not to patch up.
40#
41# Added -ac option, use -ac or -ac9 (say) to stop at a particular version
42# Dave Gilbert <linux@treblig.org>, 29th September 2001.
43#
44# Add support for (use of) EXTRAVERSION (to support 2.6.8.x, e.g.);
45# update usage message;
46# fix some whitespace damage;
47# be smarter about stopping when current version is larger than requested;
48# Randy Dunlap <rdunlap@xenotime.net>, 2004-AUG-18.
49#
50# Add better support for (non-incremental) 2.6.x.y patches;
51# If an ending version number if not specified, the script automatically
52# increments the SUBLEVEL (x in 2.6.x.y) until no more patch files are found;
53# however, EXTRAVERSION (y in 2.6.x.y) is never automatically incremented
54# but must be specified fully.
55#
56# patch-kernel does not normally support reverse patching, but does so when
57# applying EXTRAVERSION (x.y) patches, so that moving from 2.6.11.y to 2.6.11.z
58# is easy and handled by the script (reverse 2.6.11.y and apply 2.6.11.z).
