Subject: [PATCH] i386/cpu: Don't add unavailable_features to
|
||
|
|
env->user_features
|
||
|
|
|
||
|
|
Features unavailable due to absent of their dependent features should
|
||
|
|
not be added to env->user_features. env->user_features only contains the
|
||
|
|
feature explicity specified with -feature/+feature by user.
|
||
|
|
|
||
|
|
Fixes: 99e24dbdaa68 ("target/i386: introduce generic feature dependency mechanism")
