3# Linux kernel targets
4#
5# Note:  If you have any patches to apply, create the directory
6# sources/kernel-patches and put your patches in there and number
7# them in the order you wish to apply them...  i.e.
8#
9#   patches/kernel/001-my-special-stuff.bz2
10#   patches/kernel/003-gcc-Os.bz2
11#   patches/kernel/004_no-warnings.bz2
12#   patches/kernel/030-lowlatency-mini.bz2
13#   patches/kernel/031-lowlatency-fixes-5.bz2
14#   patches/kernel/099-shutup.bz2
15#   etc...
16#
17# these patches will all be applied by the patch-kernel.sh
18# script (which will also abort the build if it finds rejects)
19#  -Erik
20#
21# It will also do patch-o-matic patches, dependant on the patch-o-matic
22# TARGET and the POM_PATCHES list in the main Makefile.
23#
24# -Thomas.
