# Description: kernel.eclass rewrite for a clean base regarding the 2.6
# series of kernel with back-compatibility for 2.4
#
# Maintainer: John Mylchreest <johnm@gentoo.org>
# Copyright 2005 Gentoo Linux
#
# Please direct your bugs to the current eclass maintainer :)
# added functionality:
# unipatch - a flexible, singular method to extract, add and remove patches.
# A Couple of env vars are available to effect usage of this eclass
# These are as follows:
#
# K_USEPV - When setting the EXTRAVERSION variable, it should
# add PV to the end.
# this is useful for thigns like wolk. IE:
# EXTRAVERSION would be something like : -wolk-4.19-r1
# K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be
# automatically set within the kernel Makefile
# K_NOUSENAME - if this is set then EXTRAVERSION will not include the
# first part of ${PN} in EXTRAVERSION
# K_PREPATCHED - if the patchset is prepatched (ie: mm-sources,
# ck-sources, ac-sources) it will use PR (ie: -r5) as
# the patchset version for
# and not use it as a true package revision
# K_EXTRAEINFO - this is a new-line seperated list of einfo displays in
# postinst and can be used to carry additional postinst
# messages
# K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's
# K_SYMLINK - if this is set, then forcably create symlink anyway
#
# K_DEFCONFIG - Allow specifying a different defconfig target.
# If length zero, defaults to "defconfig".
# H_SUPPORTEDARCH - this should be a space separated list of ARCH's which
# can be supported by the headers ebuild
# UNIPATCH_LIST - space delimetered list of patches to be applied to the
# kernel
# UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
# on "<passedstring>*" and not "<passedno#>_*"
# - this should _NOT_ be used from the ebuild as this is
# reserved for end users passing excludes from the cli
# UNIPATCH_DOCS - space delimemeted list of docs to be installed to
# the doc dir
# UNIPATCH_STRICTORDER - if this is set places patches into directories of
# order, so they are applied in the order passed
