    s390, thp: remove infrastructure for handling splitting PMDs · fecffad2
    Kirill A. Shutemov authored
    With new refcounting we don't need to mark PMDs splitting.  Let's drop
    code to handle this.
    
    pmdp_splitting_flush() is not needed too: on splitting PMD we will do
    pmdp_clear_flush() + set_pte_at().  pmdp_clear_flush() will do IPI as
    needed for fast_gup.
