Dmitry Safonov 70ddf65184 x86/vdso: Zap vvar pages when switching to a time namespace 
The VVAR page layout depends on whether a task belongs to the root or
non-root time namespace. Whenever a task changes its namespace, the VVAR
page tables are cleared and then they will be re-faulted with a
corresponding layout.
