#
# Linux kernel targets
#
# 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/030-lowlatency-mini.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)
