-# Description: kernel.eclass rewrite for a clean base regarding the 2.6
-#              series of kernel with back-compatibility for 2.4
-#
-# Original author: John Mylchreest <johnm@gentoo.org>
-# Maintainer: kernel-misc@gentoo.org
-#
-# 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_NOUSEPR				- if this is set then EXTRAVERSION will not include the
-#						  anything based on ${PR}.
-# 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_EXTRAELOG			- same as K_EXTRAEINFO except using elog instead of einfo
-# K_EXTRAEWARN			- same as K_EXTRAEINFO except using ewarn instead of einfo
-# 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".
-# K_WANT_GENPATCHES		- Apply genpatches to kernel source. Provide any
-# 						  combination of "base", "extras" or "experimental".
-# K_EXP_GENPATCHES_PULL	- If set, we pull "experimental" regardless of the USE FLAG
-#						  but expect the ebuild maintainer to use K_EXP_GENPATCHES_LIST.
-# K_EXP_GENPATCHES_NOUSE	- If set, no USE flag will be provided for "experimental";
-# 						  as a result the user cannot choose to apply those patches.
-# K_EXP_GENPATCHES_LIST	- A list of patches to pick from "experimental" to apply when
-# 						  the USE flag is unset and K_EXP_GENPATCHES_PULL is set.
-# K_GENPATCHES_VER		- The version of the genpatches tarball(s) to apply.
-#						  A value of "5" would apply genpatches-2.6.12-5 to
-#						  my-sources-2.6.12.ebuild
-# K_SECURITY_UNSUPPORTED- If set, this kernel is unsupported by Gentoo Security
-# K_DEBLOB_AVAILABLE	- A value of "0" will disable all of the optional deblob
-#						  code. If empty, will be set to "1" if deblobbing is
-#						  possible. Test ONLY for "1".
-# K_PREDEBLOBBED		- This kernel was already deblobbed elsewhere.
-#						  If false, either optional deblobbing will be available
-#						  or the license will note the inclusion of freedist
-#						  code.
-# K_LONGTERM			- If set, the eclass will search for the kernel source
-#						  in the long term directories on the upstream servers
-#						  as the location has been changed by upstream
-# 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
-
-# Changing any other variable in this eclass is not supported; you can request
-# for additional variables to be added by contacting the current maintainer.
-# If you do change them, there is a chance that we will not fix resulting bugs;
-# that of course does not mean we're not willing to help.

-# @FUNCTION: econf_build
-# @USAGE: [econf flags]
-# @DESCRIPTION:
-# Sometimes we need to locally build up some tools to run on CBUILD because
-# the package has helper utils which are compiled+executed when compiling.
-# This won't work when cross-compiling as the CHOST is set to a target which
-# we cannot natively execute.
-#
-# For example, the python package will build up a local python binary using
-# a portable build system (configure+make), but then use that binary to run
-# local python scripts to build up other components of the overall python.
-# We cannot rely on the python binary in $PATH as that often times will be
-# a different version, or not even installed in the first place.  Instead,
-# we compile the code in a different directory to run on CBUILD, and then
-# use that binary when compiling the main package to run on CHOST.
-#
-# For example, with newer EAPIs, you'd do something like:
-# @CODE
-# src_configure() {
-# 	ECONF_SOURCE=${S}
-# 	if tc-is-cross-compiler ; then
-# 		mkdir "${WORKDIR}"/${CBUILD}

-# library search path.  This causes many builds to fail.
-# See bug #4411 for more info.
-#
-# Note that you should in general use the unversioned name of
-# the library (libfoo.so), as ldconfig should usually update it
-# correctly to point to the latest version of the library present.
