#OKV=original kernel version, KV=patched kernel version.  They can be the same.

#Original Kernel Version before Patches
# eg: 2.6.0-test8
OKV=${PV/_beta/-test}
OKV=${OKV/-r*//}

#Kernel version after patches
# eg: 2.6.0-test8-bk1
KV=${PF/_beta/-test}
KV=${KV/-r/-bk}
KV=${KV//${PN}-}

#version of gentoo patchset
# eg: 2.6.0-test8-r1-patchset-1
# this gets added on right at the end before it links
# if you dont want to apply these patches, set GPV=0
