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!

| 2 | # Script to apply kernel patches. | ||

| 4 | # The source directory defaults to /usr/src/linux, and the patch | ||
| 5 | # directory defaults to the current directory. | ||

| 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 | ||

| 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. | ||
