# @ECLASS-VARIABLE: K_NASPATCHES_VER
# @DESCRIPTION:
# The version of the nas patches tarball(s) to apply.
# A value of "5" would apply 2.6.12-5 to my-sources-2.6.12.ebuild
# @ECLASS-VARIABLE: K_NASKERNEL_NAME
# @DESCRIPTION:
# The kernel name used by the ebuild, it should be the ending ${PN} part
# for example, of linux-nas it is "${PN/${PN/-*}-}" (nas)

# @ECLASS-VARIABLE: K_NASKERNEL_URI_CONFIG
# @DESCRIPTION:
# Set this either to "no" or "yes" depending on the location of the
# kernel config files. If they are inside FILESDIR (old location)
# leave this option set to "no", otherwise set this to "yes"

K_KERNEL_SOURCES_PKG="${K_KERNEL_SOURCES_PKG:-${CATEGORY}/${PN/*-}-sources-${PVR}}"
# @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}.${KV_PATCH}.3.bz2
K_KERNEL_PATCH_VER="${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:-}"

# @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.

# sys-kernel/linux-vserver (vserver-sources) require this. This won't work for
# firmware pkgs.

# @DESCRIPTION:
# For every kernel binary package, there is a kernel source package associated

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

# by linux-openvz and linux-vserver
K_WORKAROUND_SOURCES_COLLISION="${K_WORKAROUND_SOURCES_COLLISION:-}"
# @ECLASS-VARIABLE: K_WORKAROUND_DIFFERENT_EXTRAVERSION
# @DESCRIPTION:
# Some kernel sources are shipped with their own EXTRAVERSION and
# we're kindly asked to not touch it, if this is your case, set
# this variable in order to make linux-mod_pkg_postinst happy
# (update_depmod) by feeding it with valid KV_FULL, that will be
# calculated using EXTRAVERSION in Makefile.
