Tag kernel26-2.6.12-alx-r9
1 | #! /bin/sh |
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. |
26 | # |
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 <rddunlap@osdl.org>, 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). |
