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.
