Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+# 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 <rddunlap@osdl.org>, 2004-AUG-18.
