New Revision: 216455
URL: http://svn.freebsd.org/changeset/base/216455
Log:
MFC r216394:
In fpudna()/npxdna(), mark FPU context initialized and optionally
mark user FPU context initialized, if current context is user context.
It was reversed in r215865, by inadequate change of this code fragment
to a call to fpuuserinited()/npxuserinited().
