ARM uses custom implementation of PMD folding in 2-level page table case. Generic code expects to see __PAGETABLE_PMD_FOLDED to be defined if PMD is folded, but ARM doesn't do this. Let's fix it. Defining __PAGETABLE_PMD_FOLDED will drop out unused __pmd_alloc(). It also fixes problems with recently-introduced pmd accounting on ARM without LPAE. Signed-off-by: Kirill A.
