-# @SUPPORTED_EAPIS: 6 7 8
-# @BLURB: Eclass for kernel packages
-# @DESCRIPTION:
-# This is the kernel.eclass rewrite for a clean base regarding the 2.6
-# series of kernel with back-compatibility for 2.4
-# Please direct your bugs to the current eclass maintainer :)
-# added functionality:
-# unipatch		- a flexible, singular method to extract, add and remove patches.
-
-# @ECLASS_VARIABLE: K_USEPV
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# When setting the EXTRAVERSION variable, it should
-# add PV to the end.
-# this is useful for things like wolk. IE:
-# EXTRAVERSION would be something like : -wolk-4.19-r1
-
-# @ECLASS_VARIABLE:  K_NODRYRUN
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# if this is set then patch --dry-run will not
-# be run. Certain patches will fail with this parameter
-# See bug #507656
-
-# @ECLASS_VARIABLE:  K_NOSETEXTRAVERSION
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# if this is set then EXTRAVERSION will not be
-# automatically set within the kernel Makefile
-
-# @ECLASS_VARIABLE: K_NOUSENAME
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# if this is set then EXTRAVERSION will not include the
-# first part of ${PN} in EXTRAVERSION
-
-# @ECLASS_VARIABLE: K_NOUSEPR
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# if this is set then EXTRAVERSION will not include the
-# anything based on ${PR}.
-
-# @ECLASS_VARIABLE: K_PREPATCHED
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# if the patchset is prepatched (ie: pf-sources,
-# zen-sources etc) it will use PR (ie: -r5) as the
-# patchset version for and not use it as a true package
-# revision
-
-# @ECLASS_VARIABLE:  K_EXTRAEINFO
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# this is a new-line seperated list of einfo displays in
-# postinst and can be used to carry additional postinst
-# messages
-
-# @ECLASS_VARIABLE:  K_EXTRAELOG
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# same as K_EXTRAEINFO except using elog instead of einfo
-
-# @ECLASS_VARIABLE:  K_EXTRAEWARN
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# same as K_EXTRAEINFO except using ewarn instead of einfo
-
-# @ECLASS_VARIABLE:  K_SYMLINK
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# if this is set, then forcably create symlink anyway
-
-# @ECLASS_VARIABLE:  K_BASE_VER
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# for git-sources, declare the base version this patch is
-# based off of.
-
-# @ECLASS_VARIABLE:  K_DEFCONFIG
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# Allow specifying a different defconfig target.
-# If length zero, defaults to "defconfig".
-
-# @ECLASS_VARIABLE:  K_WANT_GENPATCHES
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# Apply genpatches to kernel source. Provide any
-# combination of "base", "extras" or "experimental".
-
-# @ECLASS_VARIABLE:  K_EXP_GENPATCHES_PULL
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# If set, we pull "experimental" regardless of the USE FLAG
-# but expect the ebuild maintainer to use K_EXP_GENPATCHES_LIST.
-
-# @ECLASS_VARIABLE:  K_EXP_GENPATCHES_NOUSE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# If set, no USE flag will be provided for "experimental";
-# as a result the user cannot choose to apply those patches.
-
-# @ECLASS_VARIABLE:  K_EXP_GENPATCHES_LIST
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# A list of patches to pick from "experimental" to apply when
-# the USE flag is unset and K_EXP_GENPATCHES_PULL is set.
-
-# @ECLASS_VARIABLE:  K_FROM_GIT
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# If set, this variable signals that the kernel sources derives
-# from a git tree and special handling will be applied so that
-# any patches that are applied will actually apply.
-
-# @ECLASS_VARIABLE:  K_GENPATCHES_VER
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# The version of the genpatches tarball(s) to apply.

-
-# @ECLASS_VARIABLE:  K_SECURITY_UNSUPPORTED
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# If set, this kernel is unsupported by Gentoo Security
-# to the current eclass maintainer :)
-
-# @ECLASS_VARIABLE:  K_DEBLOB_AVAILABLE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# 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".
-
-# @ECLASS_VARIABLE:  K_DEBLOB_TAG
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# This will be the version of deblob script. It's a upstream SVN tag
-# such asw -gnu or -gnu1.
-
-# @ECLASS_VARIABLE:  K_PREDEBLOBBED
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# This kernel was already deblobbed elsewhere.
-# If false, either optional deblobbing will be available
-# or the license will note the inclusion of linux-firmware code.
-
-# @ECLASS_VARIABLE:  K_LONGTERM
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# 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
-
-# @ECLASS_VARIABLE:  H_SUPPORTEDARCH
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# this should be a space separated list of ARCH's which
-# can be supported by the headers ebuild
-
-# @ECLASS_VARIABLE:  UNIPATCH_LIST
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# space delimetered list of patches to be applied to the kernel
-
-# @ECLASS_VARIABLE:  UNIPATCH_EXCLUDE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# 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
-
-# @ECLASS_VARIABLE:  UNIPATCH_DOCS
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# space delimemeted list of docs to be installed to
-# the doc dir
-
-# @ECLASS_VARIABLE:  UNIPATCH_STRICTORDER
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# 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.
