Comment 27 for bug 368809

And here's the script.

Just make sure that the ignore_nice_load.patch file is in the PATCH_DIR, and that the BUILD_DIR has a decent amount of free space. You may also want to change CONCURRENCY_LEVEL to suit the number of processing cores you have.

This has not been extensively tested (I used it exactly once to build my current kernel), so use at your own risk.
