-# Note:  If you have any patches to apply, create the directory
-# sources/kernel-patches and put your patches in there and number
-# them in the order you wish to apply them...  i.e.
-#
-#   sources/kernel-patches/001-my-special-stuff.bz2

-#   sources/kernel-patches/031-lowlatency-fixes-5.bz2
-#   sources/kernel-patches/099-shutup.bz2
-#   etc...
-#
-# these patches will all be applied by the patch-kernel.sh
-# script (which will also abort the build if it finds rejects)
