The extended PTFF features (qsie, qtoue, stoe, stoue) are dependent
b38b0f
on the multiple-epoch facility (mepoch). Let's print a warning if these
b38b0f
features are enabled without mepoch.
b38b0f
b38b0f
While we're at it, let's move the FEAT_GROUP_INIT for mepochptff down
b38b0f
the s390_feature_groups list so it can be properly indexed with its
b38b0f
generated S390FeatGroup enum.
