# Script to apply kernel patches.
|
|
# usage: patch-kernel [ sourcedir [ patchdir [ stopversion ] [ -acxx ] ] ]
|
|
# The source directory defaults to /usr/src/linux, and the patch
|
|
# directory defaults to the current directory.
|
|
# e.g.
|
|
# scripts/patch-kernel . ..
|
|
# Update the kernel tree in the current directory using patches in the
|
|
# directory above to the latest Linus kernel
|
|
# scripts/patch-kernel . .. -ac
|
|
# Get the latest Linux kernel and patch it with the latest ac patch
|
|
# scripts/patch-kernel . .. 2.4.9
|
|
# Gets standard kernel 2.4.9
|
|
# scripts/patch-kernel . .. 2.4.9 -ac
|
|
# Gets 2.4.9 with latest ac patches
|
|
# scripts/patch-kernel . .. 2.4.9 -ac11
|
|
# Gets 2.4.9 with ac patch ac11
|
|
# Note: It uses the patches relative to the Linus kernels, not the
|
|
# ac to ac relative patches
|
|
#
|
|
# It determines the current kernel version from the top-level Makefile.
|
|
# It then looks for patches for the next sublevel in the patch directory.
|
|
# This is applied using "patch -p1 -s" from within the kernel directory.
|
|
# A check is then made for "*.rej" files to see if the patch was
|
|
# successful. If it is, then all of the "*.orig" files are removed.
|
|
#
|
|
# Nick Holloway <Nick.Holloway@alfie.demon.co.uk>, 2nd January 1995.
|
|
#
|
|
# Added support for handling multiple types of compression. What includes
|
|
# gzip, bzip, bzip2, zip, compress, and plaintext.
|
|
#
|
|
# Adam Sulmicki <adam@cfar.umd.edu>, 1st January 1997.
|
|
#
|
|
# Added ability to stop at a given version number
|
|
# Put the full version number (i.e. 2.3.31) as the last parameter
|
|
# Dave Gilbert <linux@treblig.org>, 11th December 1999.
|
|
|
|
# Fixed previous patch so that if we are already at the correct version
|
|
# not to patch up.
|
|
#
|
|
# Added -ac option, use -ac or -ac9 (say) to stop at a particular version
|
|
# Dave Gilbert <linux@treblig.org>, 29th September 2001.
|
|
#
|
|
# Add support for (use of) EXTRAVERSION (to support 2.6.8.x, e.g.);
|
|
# update usage message;
|
|
# fix some whitespace damage;
|
|
# be smarter about stopping when current version is larger than requested;
|
|
# Randy Dunlap <rdunlap@xenotime.net>, 2004-AUG-18.
|
|
#
|
|
# Add better support for (non-incremental) 2.6.x.y patches;
|
|
# If an ending version number if not specified, the script automatically
|
|
# increments the SUBLEVEL (x in 2.6.x.y) until no more patch files are found;
|
|
# however, EXTRAVERSION (y in 2.6.x.y) is never automatically incremented
|
|
# but must be specified fully.
|
|
#
|
|
# patch-kernel does not normally support reverse patching, but does so when
|
|
# applying EXTRAVERSION (x.y) patches, so that moving from 2.6.11.y to 2.6.11.z
|
|
# is easy and handled by the script (reverse 2.6.11.y and apply 2.6.11.z).
