15# 17#
18# K_USEPV - When setting the EXTRAVERSION variable, it should
19# add PV to the end.
20# this is useful for thigns like wolk. IE:
21# EXTRAVERSION would be something like : -wolk-4.19-r1
16# K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be automatically set within the kernel Makefile 22# K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be
23# automatically set within the kernel Makefile
17# K_NOUSENAME - if this is set then EXTRAVERSION will not include the first part of ${PN} in EXTRAVERSION 24# K_NOUSENAME - if this is set then EXTRAVERSION will not include the
18# 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 EXTRAVERSION 25# first part of ${PN} in EXTRAVERSION
26# K_NOUSEPR - if this is set then EXTRAVERSION will not include the
27# anything based on ${PR}.
28# K_PREPATCHED - if the patchset is prepatched (ie: mm-sources,
29# ck-sources, ac-sources) it will use PR (ie: -r5) as
30# the patchset version for
19# - and not use it as a true package revision 31# and not use it as a true package revision
20# K_EXTRAEINFO - this is a new-line seperated list of einfo displays in postinst and can be used to carry additional postinst messages 32# K_EXTRAEINFO - this is a new-line seperated list of einfo displays in

21# K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's 35# K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's
36# K_SYMLINK - if this is set, then forcably create symlink anyway
37#
38# K_DEFCONFIG - Allow specifying a different defconfig target.
39# If length zero, defaults to "defconfig".
40# K_WANT_GENPATCHES - Apply genpatches to kernel source. Provide any
41# combination of "base" and "extras"
42# K_GENPATCHES_VER - The version of the genpatches tarball(s) to apply.
43# A value of "5" would apply genpatches-2.6.12-5 to
44# my-sources-2.6.12.ebuild

51# UNIPATCH_EXCLUDE - an addition var to support exlusion based completely
52# on "<passedstring>*" and not "<passedno#>_*"
53# - this should _NOT_ be used from the ebuild as this is
54# reserved for end users passing excludes from the cli
