[PATCH 8/9] x86/fpu: remove __fpregs_(de)activate

From: riel
Date: Tue Oct 04 2016 - 20:35:07 EST


From: Rik van Riel <riel@xxxxxxxxxx>

Now that fpregs_activate and fpregs_deactivate do nothing except
call the double underscored versions of themselves, we can get
rid of the double underscore version.
