-# 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@g.o>
-# Maintainer: kernel-misc@g.o
-#
-# 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" and "extras"
-# 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

-# This function handles the basics of setting the SRC_URI for a gcc ebuild.
-# To use, set SRC_URI with:
-#
-#	SRC_URI="$(get_gcc_src_uri)"
-#
-# Other than the variables normally set by portage, this function's behavior
-# can be altered by setting the following:
-#
-#	SNAPSHOT
-#			If set, this variable signals that we should be using a snapshot
-#			of gcc from ftp://sources.redhat.com/pub/gcc/snapshots/. It is
-#			expected to be in the format "YYYY-MM-DD". Note that if the ebuild
-#			has a _pre suffix, this variable is ignored and the prerelease
-#			tarball is used instead.
-#
-#	BRANCH_UPDATE
-#			If set, this variable signals that we should be using the main
-#			release tarball (determined by ebuild version) and applying a
-#			CVS branch update patch against it. The location of this branch
-#			update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
-#			Just like with SNAPSHOT, this variable is ignored if the ebuild
-#			has a _pre suffix.
-#
-#	PATCH_VER
-#	PATCH_GCC_VER
-#			This should be set to the version of the gentoo patch tarball.
-#			The resulting filename of this tarball will be:
-#			gcc-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
-#
-#	PIE_VER
-#	PIE_GCC_VER
-#			These variables control patching in various updates for the logic
-#			controlling Position Independant Executables. PIE_VER is expected
-#			to be the version of this patch, and PIE_GCC_VER the gcc version of
-#			the patch:
-#			An example:
-#					PIE_VER="8.7.6.5"
-#					PIE_GCC_VER="3.4.0"
-#			The resulting filename of this tarball will be:
-#			gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
-#
-#	SPECS_VER
-#	SPECS_GCC_VER
-#			This is for the minispecs files included in the hardened gcc-4.x
-#			The specs files for hardenedno*, vanilla and for building the "specs" file.
-#			SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER
-#			the gcc version of the patch.
-#			An example:
-#					SPECS_VER="8.7.6.5"
-#					SPECS_GCC_VER="3.4.0"
-#			The resulting filename of this tarball will be:
-#			gcc-${SPECS_GCC_VER:-${GCC_RELEASE_VER}}-specs-${SPECS_VER}.tar.bz2
-#
-#	HTB_VER
-#	HTB_GCC_VER
-#			These variables control whether or not an ebuild supports Herman
-#			ten Brugge's bounds-checking patches. If you want to use a patch
-#			for an older gcc version with a new gcc, make sure you set
-#			HTB_GCC_VER to that version of gcc.
