-# Linux kernel targets
+# Linux kernel target for the OpenWRT project
 #
-# 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/003-gcc-Os.bz2
-#   sources/kernel-patches/004_no-warnings.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)
-#  -Erik
+# patches are sorted by numbers
+# 000	patch between linux-2.4.xx and linux-mips-cvs
+# 0xx	linksys patches
+# 1xx	OpenWRT patches (diag,compressed,..)
+# 2xx	fixes for wl driver integration
+# 3xx	kernel feature patches (squashfs,jffs2 compression,..)
+# 4xx	patches needed to integrate feature patches
