-# @ECLASS-VARIABLE: K_ROGKERNEL_NAME
-# @DESCRIPTION:
-# The kernel name used by the ebuild, it should be the ending ${PN} part
-# for example, of linux-kogaion it is "${PN/${PN/-*}-}" (kogaion)
-K_ROGKERNEL_NAME="${K_ROGKERNEL_NAME:-${PN/${PN/-*}-}}"
-
-# @ECLASS-VARIABLE: K_ROGKERNEL_SELF_TARBALL_NAME
-# @DESCRIPTION:
-# If the main kernel sources tarball is generated in-house and available
-# on the "kogaion" mirror, set this variable to the extension name (see example
-# below). This will disable ALL the extra/local patches (since they have to
-# be applied inside the tarball). Moreover, K_ROGKERNEL_NAME,
-# K_KERNEL_PATCH_VER will be ignored.
-# Example:
-#   K_ROGKERNEL_SELF_TARBALL_NAME="kogaion"
-#   This would generate:
-#   SRC_URI="mirror://kogaion/sys-kernel/linux-${PV}+kogaion.tar.${K_TARBALL_EXT}"
-K_ROGKERNEL_SELF_TARBALL_NAME="${K_ROGKERNEL_SELF_TARBALL_NAME:-}"
-
-# @ECLASS-VARIABLE: K_ROGKERNEL_PATCH_UPSTREAM_TARBALL
-# @DESCRIPTION:
-# If set to 1, the ebuild will fetch the upstream kernel tarball and
-# apply the RogentOS patch against it. This strategy avoids the need of
-# creating complete kernel source tarballs. The default value is 0.
-K_ROGKERNEL_PATCH_UPSTREAM_TARBALL="${K_ROGKERNEL_PATCH_UPSTREAM_TARBALL:-0}"
-
-# @ECLASS-VARIABLE: K_ROGKERNEL_FORCE_SUBLEVEL

-K_ROGKERNEL_FORCE_SUBLEVEL="${K_ROGKERNEL_FORCE_SUBLEVEL:-}"
-
-# @ECLASS-VARIABLE: K_ROGKERNEL_RESET_EXTRAVERSION
-# @DESCRIPTION:
-# Force the rewrite of EXTRAVERSION in kernel sources Makefile (setting it to "")
-K_ROGKERNEL_RESET_EXTRAVERSION="${K_ROGKERNEL_RESET_EXTRAVERSION:-}"
-
-# @ECLASS-VARIABLE: K_ROGKERNEL_LONGTERM

-
-# @ECLASS-VARIABLE: K_KERNEL_PATCH_VER
-# @DESCRIPTION:
-# If set to "3" for example, it applies the upstream kernel
-# patch corresponding to patch-${KV_MAJOR}.${KV_MINOR}.${KV_PATCH}.3.${K_TARBALL_EXT}
-# @TODO: deprecate and remove once 2.6.x kernels are retired
-K_KERNEL_PATCH_VER="${K_KERNEL_PATCH_VER:-}"
-
-# @ECLASS-VARIABLE: K_KERNEL_PATCH_HOTFIXES
-# @DESCRIPTION:
-# If there is the need to quickly apply patches to the kernel
-# without bumping the kernel patch tarball (for eg. in case
-# of just released security fixes), set this variable in your ebuild
-# pointing to space separated list of patch paths.
-K_KERNEL_PATCH_HOTFIXES="${K_KERNEL_PATCH_HOTFIXES:-}"
-
-# @ECLASS-VARIABLE: K_KERNEL_DISABLE_PR_EXTRAVERSION
-# @DESCRIPTION:
-# Set this to "1" if you want to tell kernel-2 eclass to
-# not use ${PR} in kernel EXTRAVERSION (K_NOUSEPR). Otherwise, set
-# this to "0" to not set K_NOUSEPR at all.
-K_KERNEL_DISABLE_PR_EXTRAVERSION="${K_KERNEL_DISABLE_PR_EXTRAVERSION:-1}"
-
-# @ECLASS-VARIABLE: K_KERNEL_SLOT_USEPVR

-# firmware pkgs.
-K_KERNEL_SLOT_USEPVR="${K_KERNEL_SLOT_USEPVR:-0}"
-
-# @ECLASS-VARIABLE: K_KERNEL_NEW_VERSIONING
-# @DESCRIPTION:
-# Set this to "1" if your kernel ebuild uses the new Linux kernel upstream
-# versioning and ${PV} contains the stable revision, like 3.7.1.
-# In the example above, this makes the SLOT variable contain only "3.7".
-# The sublevel version can be forced using K_ROGKERNEL_FORCE_SUBLEVEL
-K_KERNEL_NEW_VERSIONING="${K_KERNEL_NEW_VERSIONING:-1}"
-
-# @ECLASS-VARIABLE: K_KERNEL_IMAGE_NAME

-K_KERNEL_IMAGE_NAME="${K_KERNEL_IMAGE_NAME:-}"

-# shall be appended to ${PROVIDE}.
-K_KERNEL_LTS="${K_KERNEL_LTS:-}"
-
-# @ECLASS-VARIABLE: K_KERNEL_IMAGE_PATH

-
-# @ECLASS-VARIABLE: K_ONLY_SOURCES

-K_WORKAROUND_SOURCES_COLLISION="${K_WORKAROUND_SOURCES_COLLISION:-}"
-
-# @ECLASS-VARIABLE: K_WORKAROUND_USE_REAL_EXTRAVERSION

-# this variable and depmod will work correctly.
