 # 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;
