Kirill A. Shutemov 7aa9a23c69 powerpc, thp: remove infrastructure for handling splitting PMDs 
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.
