[PATCH 01/34] x86: add missed pgtable_pmd_page_ctor/dtor calls for preallocated pmds

I've missed that we preallocate few pmds on pgd_alloc() if X86_PAE enabled. Let's add missed constructor/destructor calls. I haven't noticed it during testing since prep_new_page() clears page->mapping and therefore page->ptl. It's effectively equal to spin_lock_init(>ptl). Signed-off-by: Kirill

I've missed that we preallocate few pmds on pgd_alloc() if X86_PAE enabled. Let's add missed constructor/destructor calls. I haven't noticed it during testing since prep_new_page() clears page-mapping and therefore page-ptl. It's effectively equal to spin_lock_init(page-ptl). Signed-off-by:
